BEIJING (Reuters) – China announced on Wednesday that its parliament will open a key annual session on May 22, signalling that Beijing sees the country returning to normal after being reduced to a near-standstill for months by the COVID-19 epidemic.
During the gathering of the National People’s Congress in the capital, delegates will ratify major legislation, and the government will unveil economic targets, set defence spending projections and make personnel changes. The ruling Communist Party also typically announces signature policy initiatives.
The session was initially scheduled to start on March 5 but was postponed due to COVID-19, which has infected nearly 83,000 people and killed more than 4,600 on the mainland after emerging late last year in the central city of Wuhan.
As the epidemic has subsided, economic and social life gradually returned to normal, making it possible for the congress to convene, the official Xinhua news agency quoted the standing committee of the NPC, the legislature’s top decision-making body, as saying.
The committee also appointed Huang Runqiu as the new minister for ecology and environment, a post vacated when predecessor Li Ganjie became deputy Communist Party chief for Shandong province earlier this month, Xinhua reported.
Tang Yijun was also named as the new justice minister to replace Fu Zhenghua, who has reached the retirement age of 65 for ministers.
The Chinese People’s Political Consultative Conference (CPPCC), an advisory body to parliament, has proposed starting its annual session a day before the parliamentary session opens.
Analysts expect China to roll out additional fiscal stimulus in order to cushion the blow from COVID-19, which has developed in to a worldwide pandemic that some fear will trigger a severe global recession.
China’s economy contracted for the first time on record during the January-March period, when the government imposed severe travel and transport restriction to curb the spread of the epidemic.
Parliament is also expected to discuss the anti-government protests in Hong Kong, amid growing speculation that Beijing take steps to strengthen its grip on the city.
It is unclear how long parliament and its advisory body will meet for this time, and people familiar with the matter have told Reuters that this year’s annual sessions could be the shortest in decades due to COVID-19 concerns. Usually more than 5,000 delegates descend on Beijing from all over China for at least 10 days.
Beijing city plans to ease quarantine rules as early as Thursday, two sources familiar with the situation told Reuters, ahead of the key political meetings.
People arriving in the capital from other parts of China will no long have to be quarantined for two weeks unless they come from high-risk areas such as Heilongjiang in the north and some parts of Guangdong in the southeast, the sources said.

- US National Security Adviser recently said an unnamed Chinese fighter ‘looks a lot like the F-35 … because it is the F-35’
- The PLA’s only active stealth fighter the J-20 looks rather different to its US counterpart, but the FC-31 prototype may be closer to the mark

US National Security Adviser John Bolton recently accused China of stealing US technology to make a stealth fighter, a charge Beijing has denied.
On a visit to Ukraine last week, Bolton said an unnamed fifth-generation aircraft “looks a lot like the F-35, that’s because it is the F-35. They just stole it”.
At present China’s only active stealth fighter, the J-20 or Mighty Dragon, looks very different to the F-35 because it has two nose canards – which are not found on any modern US fighters – and it is larger and around 50 per cent heavier.
However, Bolton might have had another fighter in mind – the Shenyang FC-31 Gyrfalcon, which is still in the prototype phase.

The FC-31 is made by the Shenyang Aircraft Design and Research Institute, a branch of the state-owned Aviation Industry Corporation of China.
The aircraft, which made its maiden flight in 2012, has broadly similar specifications to the F-35 although it does have twin engines rather than the American jet’s single engine.
The Chinese fighter has a maximum take off weight of 25 tonnes, a combat range of 1,200km (746 miles) and a top speed of Mach 1.8, or 2,205km/h (1,370mph), whereas the US fighter’s take-off weight varies between 27 and 32 tonnes, has a top speed of Mach 1.6 and a range of up to 2,200km (1,367 miles).
The FC-31 has a weapons payload of 8 tonnes, compared with 6.8 to 8.1 tonnes for the different varieties of F-35, and a service life of up to 30 years.
Lockheed Martin, which makes the American stealth fighter, has produced three different varieties – the land-based f-35A and two for use on ships: the vertical jump F-35B and catapult-assisted F-35C.
While the Chinese jet was primarily designed for the use of the air force, its light weight also means it could be adapted for use on carriers.
It was reported to have been in the running to be used on China’s next-generation aircraft carriers, but military sources recently said it would lose out to the J-20 because of its slow pace of development and reports of technological problems.

However, the Chinese manufacturer is already actively marketing the fighter to other countries and a model of the plane appeared at the Paris Air Show in June.
One official from the Aviation Industry Corporation of China who attended the Air Show told state media that the firm hoped to “seize some share in the military aircraft market of developed nations”.
One area where the plane does have a definite advantage over its American counterpart is price. The price of a single FC-31 is expected to be about US$70 million, significantly less than the F-35 which has a price tag of around US$100 million per unit.
The US also restricts sales of the fighter to its allies, leaving a potential gap in the market for China to exploit when the fighter is ready for use.

- New material is almost identical in structure to human enamel, which does not regenerate itself
- Crystal-like mineral can grow on teeth and last permanently, researchers say

Scientists at a Chinese university say they have discovered the world’s first material that can repair damaged tooth enamel once and last for life.
A few drops of the liquid solution can fix all invisible cracks and wear on an ageing molar, according to researchers at Zhejiang University in Hangzhou, eastern China, whose work was published on Friday in the journal Science Advances.
The material, calcium phosphate ion clusters, can grow a thin layer of protective shield on teeth, the research showed. The transparent, crystal-like mineral has a structure resembling fish scales and a high mechanical strength – almost identical to the enamel on a human tooth.
Its repair of the tooth “would be permanent”, wrote the researchers, led by Professor Tang Ruikang at the university’s chemistry department.

The technology could be developed as an effective remedy in clinical practice for enamel erosion, the main cause of tooth decay, Tang’s team said. Tooth decay affects almost half of the world’s population, costing dental patients in the United States and European Union a combined US$200 billion annually, according to the World Dental Federation.
Enamel, the outer covering of teeth, is the hardest tissue in the human body, protecting teeth during biting and chewing food.
Unlike other tissues such as muscle, bone and skin, enamel is generated by cells that die immediately after completing their job. The human body cannot produce more of them, so when enamel breaks or chips, it will not regenerate itself.
For decades, researchers around the world have conducted studies to seek a solution, but the artificial materials tested previously could not recreate precisely the fine structure of natural enamel, leaving gaps or holes that could cause it to break off real enamel.
Wouldn’t it be nice if our teeth fixed themselves, just like pandas’ do?
Tang’s team claim their new material can grow seamlessly on human teeth. They mixed two different types of repairing material together to form tiny clusters of mineral particles only 1.5 nanometres in diameter – smaller than a strand of human DNA.
Unlike in previous experiments, these clusters could remain stable for a long time without clumping together, making precise reconstruction of an enamel-like structure possible.
Chen Haifeng, associate professor at Peking University’s biomedical engineering department, said that the research was a positive step but that the new material might need improvements before clinical use.
For instance, the artificial layer requires two days to grow, which could be difficult for dentists to schedule with patients.
Many children use so much toothpaste it’s unhealthy, experts warn
The liquid solution contains triethylamine, a toxic substance with a very strong smell, which may pose a health risk, according to Chen. “But it doesn’t mean we can’t do anything,” he said.
The researchers said the chemical would quickly vaporise and none would be left in the teeth after the protective shield had formed.
Some products preventing enamel erosion and decay, such as toothpaste with enamel-strengthening ingredients, are already available in shops.
“Prevention is the best approach,” Chen said. “We should never wait until the damage is done. Our teeth are a miracle of nature. Artificial replacement will never do the job as well.”
