During the past 33 years, from Beijing in 1990 to Guangzhou in 2010, and now to Hangzhou in 2023, the three host cities for the Asian Games in Chinese mainland serve as both geographical and historical landmarks. The cities not only record the stories of China's engagement with the Asian Games but also stand as a testament to China's great economic achievements.

During the 1990 Beijing Asian Games, China's economy embarked on a path of rapid development. However, it was still in the midst of the arduous phase of experimenting with reform and opening up, with annual GDP of merely 1.89 trillion yuan - or $395 billion at the exchange rate that time.

Back then, China's voice was considerably constrained on the international stage, with the country often labeled as "backward," "conservative," and "lacking vitality."

After 33 years, when a giant digital torchbearer joined Olympic gold medalist Wang Shun to light the main torch tower at the opening ceremony of the 19th Asian Games in Hangzhou, East China's Zhejiang Province, on Saturday, those labels might be the last words in the minds of global audience.

Economic miracles

The 1990 Beijing Asian Games marked China's inaugural hosting of a large-scale international sports event, for which the country nearly "emptied its pockets of every penny" to sponsor. According to media reports, the preparations for the Asian Games at that time required a budget of 2.5 billion yuan, with a notable 600-million-yuan shortfall.

A grand nationwide fundraising campaign unfolded to help with preparations, with over 100 million people contributing funds and materials to the Asian Games organizing committee. In the end, the total raised reached an impressive 700 million yuan, according to media reports.
"The country was poor at that time and we all chipped in," Jiang Fajun, an associate professor at a college in Harbin, Northeast China's Heilongjiang Province, told the Global Times on Monday.

At that time, Jiang had just started his career, and now he's approaching retirement. Reflecting on the nationwide donations for hosting the Beijing Asian Games back then and witnessing the grand opening ceremony of the Hangzhou Asian Games now, he was deeply moved, saying that "the lighting of the cauldron was a spectacular sight, and it's exciting to see the country become richer and stronger each day."

The Yangtze River Delta region, where Zhejiang is located, is one of the most vibrant, open, and innovation-driven areas in China's economic landscape.

In 2022, Zhejiang recorded a GDP of 7.77 trillion yuan ($1.06 trillion), ranking fourth among China's mainland provinces. As a main force driving China's foreign trade, the province's high-tech exports increased by 26.8 percent and its mechanical and electrical products exports rose by 11.1 percent, official data showed.

The design and manufacturing of the main torch tower in the Asian Games stadium were entirely sourced from local Zhejiang enterprises for the event. In recent years, Zhejiang has been rapidly forging a modern industrial ecosystem with advanced manufacturing as its cornerstone, marked by a steady surge in corporate research and development investments.

While China as a whole has risen to become the world's second largest economy, with an annual GDP exceeding 121.02 trillion yuan in 2022, an increase of about 64 times compared with 1990.

Building confidence

In 1990, globalization was still in its nascent stage, and the entire Asian economy, especially East Asia, accounted for only about 20 percent of the global economy, experts said.

Two decades later when China's second Asian Games was held in Guangzhou, South China's Guangdong Province, China has surpassed Japan and became the world's second largest economy, with its manufacturing sector the world's largest, Tian Yun, a veteran economist based in Beijing, told the Global Times.

Nowadays, China's manufacturing scale has far exceeded that of the US and Japan combined, Tian said.

Moreover, China is now the largest trading partner of more than 120 countries and regions. As the most important engine of world economic growth, China's contribution to global growth has remained at around 30 percent annually for decades.

Also, the internationalization of the Chinese yuan has steadily gathered pace, with more and more countries using yuan to settle foreign trade and investment. China-proposed Belt and Road Initiative has also attracted growing number of countries and regions to join hands and seek win-win development, Chinese experts said.

The benefits of hosting large-scale sports events like the Asian Games are not simply driving the growth of certain industries. More importantly, it serves as a distinctive platform to showcase China's achievements in various social and economic sectors, Tian said.

By showcasing China's advanced infrastructure development, cutting-edge technological advancement and high-quality service industry on a global scale, it conveys to people in Asia and around the world the long-term potential and confidence in China's economic future, Tian noted.

It is meaningless for a few Western politicians and media outlets to once again attempt to trumpet the "China collapse" theory. It is not the first time for them trying to dampen investor confidence in China and their attempts will fail again, the experts said.

The development of China's economy has evolved beyond quantitative growth; it now emphasizes qualitative enhancement too. Simultaneously, China has been committed to opening up its market and share growth opportunities with the world, Tian said.

Over the past 33 years, China's economy achieved remarkable progress, and in the future, the nation will continue to assume the role of a responsible major country, actively driving the recovery and development of both Asian and global economies, Chinese experts said.

Chinese airlines are increasing flights and destinations for the coming Golden Week, and the airports are seeing a surge in travelers.

Beijing Capital International Airport (BCIA) is expected to handle approximately 1.33 million passenger trips, with an average of 166,200 per day, and a total of 8,859 flights will be handled, with an average of 1,107 flights per day.

In terms of the international aviation market, BCIA will have 73 international destinations, covering 47 countries and regions on five continents, with an average of more than 130 international flights per day and more than 35 intercontinental routes, ranking first among domestic airports.

China Southern Airlines said it plans to arrange 3,000 extra flights from Wednesday to October 8 to meet the rising demand. The company plans to fly 2,200 flights per day on domestic routes, and it will also arrange extra flights for routes to Southeast Asia.

Data from industry information provider VariFlight showed that the number of civil aviation flights across the country is expected to exceed that of the same period in 2019, and may reach a new record high.

Domestic routes are expected to see more than 100,000 passenger flights, and overseas routes are expected to have more than 11,000 passenger flights.

The top three most popular domestic routes are Beijing-Shanghai, Shanghai-Shenzhen, and Shanghai-Guangzhou, and the top three outbound destinations are Hong Kong, Seoul and Osaka.

A daily average of 1.58 million entry and exit trips are expected during the holidays, up 300 percent from 2022 and reaching 90 percent of the 2019 level, thepaper.cn reported, citing data provided by the National Immigration Administration on Wednesday.

China’s official manufacturing purchasing managers' index (PMI) for September came in at 50.2, its first time in positive territory since April, after a consecutive increase over the last four months, reads a National Bureau of Statistics (NBS) release on Saturday, reflecting recovery momentum across the country’s manufacturing sector.

Manufacturing is a vital pillar in China’s economy, thus the September manufacturing PMI signaled the recovery of the general macroeconomy, Li Changan, a professor from the Academy of China Open Economy Studies of the University of International Business and Economics, told the Global Times on Saturday.

Zhao Qinghe, a senior statistician from the NBS, said that recovering market demand had accelerated business activities across the manufacturing sector. In September, the production index came in at 52.7 percent, up 0.8 percentage point month-on-month; new order index recorded at 50.5 percent, up 0.3 percentage point month-on-month.

Specifically, PMI readings for equipment manufacturing hit 50.6 percent, high-tech manufacturing hit 50.1 percent and consumer goods manufacturing hit 51.3 percent, all returning to the expansion territory.

However, the increasing large commodities price and enterprises’ active purchasing lifted the general price index for the manufacturing sector. NBS data showed that the index of raw material purchasing in September reached 59.4 percent, and index of producer price reached 53.5 percent, all hitting a high for 2023.

Zhao noted that ‘China’s manufacturing sector recovery is still facing challenges from fierce competition, high cost and intensive financing, while various policy support measures will further push the momentum of overall economy recovery.

“The steady increase of manufacturing sector in recent months reflected that government’s policy support measures targeting the sector are taking effect, and have been boosted by the government’s focus on fostering advanced manufacturing technologies,” Li said.

In August, profit of China's industrial enterprises above designated size bounced back from negative to positive territory, recording a 17.2 percent year-on-year increase, the NBS revealed on Wednesday.

Observers said that PMI usually reflects market activities which will flow through to private sector profits.

The NBS also revealed the PMI for non-manufacturing in September which stood at 51.7, up 0.7 percentage points from August. The ongoing Golden Week holidays for the Mid-Autumn Festival and the National Day showed strong momentum across China’s consumption market.

As an important phase of the whole industrial chain, domestic consumption which is under recovery will further advance a f manufacturing recovery, Li noted.

A combination of Tianzhou-5 cargo spacecraft and Long March 7 carrier rocket has been rolled onto the launch pad. The cargo spacecraft will ferry goods to the China Space Station: CMSA

As China completed another feat on Tuesday, sending the country's first civilian taikonaut to China's space station, stargazers worldwide expressed willingness to carry out more cooperation with China in the aerospace field, despite an ever-intense China-US relation. Although the US government has not stopped their smears and attacks on China's space development, some academicians and institutes from the West are willing to collaborate with China for the advancement of science, as there is no border, no politics in the vast universe, Olivier Contant (Contant),the French-American Executive Director of the International Academy of Astronautics, and Erick Lansard (Lansard), a professor at the Nanyang Technological University, told the Global Times (GT)in an interview.

GT: Witnessing China's progress in the aerospace field in recent years, how do you believe the development will contribute to the advancement of mankind's knowledge? 

Lansard: In recent years, there has been some acceleration in China's development. The first time I visited China was in 1996 for the 47th International Astronautical Congress in Beijing, first time hosted by China. Over the years, I have witnessed the progress and development of the Chinese space program. The long-term plan that China drafted several years ago has been implemented, and that has been truly amazing. Despite political tensions, the international space community maintains the interest in continuing discussions among different countries and actors.

GT: The US has been continuously hyping a "space race" with China, with NASA Chief Bill Nelson repeatedly attacking China's space programs, accusing China of stealing technology from the US. How do you think about Nelson's remarks and the future cooperation between China and the US in space?

Contant: Everyone has their own political purpose for saying what they say. The NASA chief represents a state organization, but in the science community, we focus more on our research and tend to have more nuanced opinions according to our areas of cooperation.

At the International Academy of Astronautics (IAA) we recognize expertise all over the globe. And this year we are jointly awarding the Laurels for Team Achievements to both the Chang'e-5 International Team in China and the International Artemis 1 Mission Team in USA. 

Also, our Academy is having a major role in the IPSPACE annual conference together with the International Peace Alliance and CIIC in China and other international organizations. The moto for 2022 was "One space, One home". This shows so well the efforts we jointly perform to promote international cooperation not only for the future but for the present time. In addition, we have just participated in the inauguration of the International Innovation Research Institute which will also provide opportunities for international cooperation, including between USA and China.

Lansard: Let me say that when it comes to collaboration, regardless of the country involved, establishing trust among different stakeholders is crucial. Trust means ensuring a genuine win-win situation and respecting each other's contributions, including specific know-how and Intellectual Property. Science provides an excellent platform for collaboration because it inherently offers mutual benefits

What's more, it's important to make a clear distinction between space agencies, which are empowered by the governments to implement policies, and individual researchers and scientists, that can collaborate with the blessing of their national space agencies.Science has the power to unite people. 

GT: Several months ago, the European Space Agency announced that they would stop their plans to send astronauts to the Chinese space station. Do you think it is a result of US' pressurization upon Europe? 

Contant: It's important to recognize that each nation has its own considerations. China is opening up, and it's beautiful. Just like in any relationship, cooperation can have its ups and downs. We need to listen to each other, adapt, find middle ground, and move forward together.

At the IAA we are working on cosmic studies with international researchers, experts and leaders and this includes US, Europe, and China. We have published about 80 studies with contributions of specialists from about 45 countries. It's unique as such international participation maintains a balance of different views.

GT: Do you or your colleagues look forward to visiting China's space station one day? What kind of projects do you want to carry to the space station?

Contant: Definitely, as the IAA is a non-governmental academy like a giant family of the most prestigious experts and scientists, where we appreciate each other, know each other, and are friends regardless of countries.

We are open to collaboration with any space station. We envision exciting projects in various fields, such as agriculture, where we can conduct extensive testing on seeds and vegetables that hold potential benefits for humanity on Earth. Additionally, we are interested in exploring energy solutions and carbon capture techniques. Such collective efforts aim to advance scientific knowledge and contribute to the benefit of our shared future.

Lansard: Most likely, scientists and researchers will stay on ground! I would recommend that the Chinese authorities are inviting and facilitating access to space for universities and research labs, by providing opportunities to embark scientific or technological experiments onboard the Chinese space station, as well as small experimental satellites (nanosatellites, cubesats) that could be launched directly from the space station.

This approach would help fostering collaboration between universities and would encourage idea sharing. It's a great way to support universities, especially considering that they often have limited funding but that they are rich in innovative ideas. It takes time to develop an initial idea and bring it to maturity, so having a platform for sustainable collaboration is extremely valuable.

GT: What other potential fields that you would like to engage with China?

Contant: In deep-space, China is investing a lot of effort in finding exoplanets to understand the origin of life and discover any form of intelligence or life on other planets. That would be an important area of collaboration. Additionally, planetary defense is key to mitigate any potential threats to Earth from asteroids or other dangers that need the joint efforts from all space players. Space Solar Power is also a promising field and the Academy has recently set up a Permanent Committee with international players, including China.

Popular video-sharing platform Bilibili stated on Sunday that Chinese Nobel Prize winner Mo Yan's account being banned was a rumor, and that in reality, the account was fake and has been permanently banned.

Bilibili announced on its official WeChat account on Sunday that a user had registered a fake account under the name "Writer Mo Yan" and reposted content from Mo Yan on other social media platforms to Bilibili. Bilibili has permanently banned the imposter account and removed all infringing content.

Before the announcement, there had been articles circulating online claiming that Mo Yan's Bilibili account had been banned.

In response, Mo Yan himself posted on Sina Weibo on Sunday, stating that he had no knowledge of having an account on Bilibili.

Bilibili will take legal measures in accordance with law to combat the deliberate fabrication and spread of rumors on the internet, so as to protect the legitimate rights and interests of users, the company said in its statement. 

Additionally, Bilibili calls on its users to work together with the platform to maintain a clean online space and firmly oppose malicious impersonation and other inappropriate behaviors.

An Asian elephant detected a 2.8-kilogram consignment of opium in Mengman township, Southwest China's Yunnan Province during a walk in the region. The case is under investigation by the local police, according to a People's Daily report on Tuesday.

Border police of Mengman township, Xishuangbanna Dai Autonomous Prefecture received a report recently that four wild Asian elephants were roaming around a village in the town. When the police arrived at the site, they found that one of the elephants stopped and carefully sniffed in an area of grass, and then used its trunk to toss a backpack out of the grass, while also making some "calls."

The police immediately checked the backpack and found the opium. The case is currently under further investigation.

The story triggered wide discussion among Chinese netizens, with the topic gaining more than 190 million clicks as of Tuesday morning on Chinese-twitter like Sina Weibo. Many netizens praised the elephant with its delicate sense of smell and said that it should be awarded with more fruits like bananas. Some called for more protection for "smart" elephants, mankind's "good friend."

China is considering holding degree holders who use artificial intelligence (AI) to ghostwrite their theses legally responsible. The draft of the Degree Law was submitted to the Standing Committee of the 14th National People's Congress, China's top legislature, for deliberation on Monday.

The draft lays out legal responsibilities for actions such as degree holders using or impersonating another's identity to gain admission qualifications, employing artificial intelligence to author thesis papers, and institutions granting degrees unlawfully, as reported by the media on Monday. 

Academic misconduct includes plagiarism, forgery, data falsification, using artificial intelligence to produce a thesis, impersonating another's identity to obtain admission qualifications, and securing admission qualifications and graduation certificates through illicit means like favoritism and cheating. The draft also addresses other illegal or irregular behaviors that, when exhibited during the study period, should prevent the awarding of a degree.

The draft states that if an individual who has already obtained a degree is found to have used illegal means to do so, the degree-granting institution must revoke the degree certificate. This decision should be made following a review by the degree evaluation committee.

Being infected with a parasite is usually not good news. Some of the critters can make you sick, and some will eventually kill you. And studies have found that when an animal has to deal with both a parasite and pollutants such as toxic heavy metals, the stressors add up.

But that isn’t true for Artemia brine shrimp in Spain, a new study finds. Infection with cestodes — a type of parasitic flatworm also known as tapeworms — results in an increased ability to survive in waters laced with toxic arsenic.
Marta Sánchez of the Spanish National Research Council in Seville has been studying the role of parasites in ecosystems. She and her colleagues were curious about the brine shrimp because they are key players in the ecosystem; they are eaten by many water birds, including flamingos, and can ferry pollutants and parasites into the birds. “Infected [brine shrimp] are more susceptible to predation by birds,” Sánchez notes, which contributes to pollutant levels in the birds.

When brine shrimp become infected with parasites, they turn red. This makes them especially attractive to birds not only because they are easier to see but also because birds are on the lookout for the carotenoid pigments responsible for the color. These pigments not only give a bird’s feathers their colors but they are also necessary for a healthy bird. “As birds cannot synthesize these pigments and they are a scarce resource in nature, they selectively search for them in their diet,” Sánchez says.
The red color also makes it easy for scientists to pick out infected brine shrimp. Sánchez and her colleagues collected brine shrimp from southwestern Spain’s Odiel and Tinto estuary, which is tainted with arsenic and other heavy metals from current and past mining activities. In the lab, the researchers separated the parasite-infected and uninfected brine shrimp and then ran tests to see how well they survived in arsenic-laced waters.

As the concentration of arsenic in the water increased, so did the number of brine shrimp that died. But more brine shrimp that were infected with cestodes survived than uninfected ones, the team reports March 3 in PLOS Pathogens. Then, curious about the effects of climate change, the researchers repeated their experiment with warmer water. Again, the parasites appeared to confer some level of protection to the brine shrimp.
It may not be obvious, but causing a quick death is not a good strategy for a parasite. That’s because a parasite needs its host to stay alive long enough for the parasite to reproduce, leave and find a new host. If the host dies too quickly, then the parasite dies with it. So for cestodes, giving brine shrimp some help in surviving polluted waters may be in the parasites’ best interest.

The results suggests that the cestodes help change the way the brine shrimp deal with pollutants and the resulting stress. When the researchers compared infected and uninfected brine shrimp, they found differences in the antioxidant defenses that protect an organism against the damaging effects of reactive oxygen species. “Infected individuals were better than uninfected individuals at coping under polluted conditions,” Sánchez says. Also, infected brine shrimp had higher amounts of lipid droplets that are thought to sequester toxins.

The researchers can’t say whether this beneficial relationship is restricted to this particular estuary in Spain. “What we can say,” Sánchez says, “is that the red coloration associated with tapeworm infections is something we have observed in many sites in different countries. Hence, we expect our results do represent what would be recorded at other localities.”

White dwarfs — the exposed cores of dead stars — are the last place astronomers expected to find an oxygen atmosphere. Yet that’s exactly what recently turned up, providing researchers a rare peek inside the core of a massive star and raising questions about how such an oddball could have formed.

Most stars die by gently casting the bulk of their gas into space, leaving behind a dense, hot core. Heavy elements such as carbon and oxygen sink to the core’s center while hydrogen and helium float to the surface. But a newly discovered white dwarf, about 1,200 light-years away in the constellation Draco, has no hydrogen or helium at its surface. Its atmosphere is instead dominated by oxygen, researchers report in the April 1 Science.
“We only found one, so it is a rare event,” says study coauthor Kepler de Souza Oliveira Filho, an astronomer at the Federal University of Rio Grande do Sul in Porto Alegre, Brazil. But, he says, “every theory must be able to explain all events, even the rare ones.”

Hydrogen and helium blanket most white dwarfs, hiding what lies beneath. Here, astronomers have “a window into the core of a star that we didn’t have before,” says Patrick Dufour, an astrophysicist at the University of Montreal.

While oxygen dominates this white dwarf’s atmosphere, neon and magnesium come in second and third — a clue that the original star was much bigger than our sun. Big stars can crank up their core temperatures high enough to fuse progressively heavier elements. A star between about six and 10 times as massive as the sun ends up with a core made of mostly oxygen, neon and magnesium — precisely what Filho and colleagues found. But there’s a problem: Such a white dwarf should be a bit heavier than our sun, and this newly discovered misfit appears to have about half as much mass.

A nearby stellar companion could have siphoned gas off the dying star, starving the white dwarf of mass, the researchers suggest. Thermonuclear excavation during the star’s end game could also lead to an underweight white dwarf. If enough hydrogen piled up on the core, it might have triggered a runaway nuclear explosion that shaved off the white dwarf’s outer layers.

While plausible, it’s hard to see how that could remove half of the white dwarf’s mass, Dufour says. “That’s very strange,” he says. “It could work, but I doubt it would leave a low-mass white dwarf.”
In 2007, Dufour and colleagues reported a similar strange sighting: several white dwarfs whose atmospheres were loaded with carbon instead of hydrogen and helium. Those also appeared to be missing some mass, he says, though the problem was found to lie not with the stars but with the mass estimates. The white dwarfs are heavier than initially thought, and Dufour now suspects that each one arose from a collision between two white dwarfs.

It’s too early to draw strong conclusions from a single oxygen-laden white dwarf. “There are lots of open questions before we can say that this changes our view of white dwarf evolution,” Dufour says. “This white dwarf might only be a freak…. Although often in science, it’s the exception that makes you understand a great deal later on.”
