If China can successfully prevent a new outbreak in Beijing, China can declare its strategy to prevent Covid-19 effectively.

Beijing is re-imposing blockade measures on dozens of neighborhoods and conducting mass testing after a new outbreak of Covid-19 broke out from the city's biggest Tan Phat Dia agricultural wholesale wholesale market.

Since June 11, Beijing health authorities have detected 106 new cases of Covid-19 related to the outbreak, which transports food to markets, supermarkets and restaurants across Beijing and the city with 21 million

The disease has also spread to Liaoning and Hebei provinces, where at least 5 nCoV-positive cases have been reported in close contact with patients in Beijing.

China's state-run media has long praised the "effective measures" it has taken in its efforts to prevent and curb the epidemic, comparing the success it achieved with the failure of its governments.

Many worry that the nCoV abruptly broke out in Beijing, once considered one of the safest cities in the country, will once again cause all of China to freeze, causing the economy to freeze.

At a government meeting on June 14, Chinese Deputy Prime Minister Ton Xuan Lan said the risk of a second outbreak was "very high" as Tan Phat Dia market was densely packed and goods were rotated.

Fengtai County, where Tan Phat Dia market is located, announced on June 13 that it will apply a "war mechanism" and establish a "headquarters" to contain the virus.

On social media, the Global Times, a newspaper belonging to the People's Daily, the Communist Party's mouthpiece, posted a video showing armed police wearing masks masking the market after it closed.

Authorities imposed blockades with 11 residential areas near the market, prohibiting people from entering and leaving.

Phong Dai district collected samples from 8,950 people working at Tan Phat Dia market.

Authorities also tracked and sampled nearly 30,000 people who had been to the market for 14 days before the market closed.

The Beijing government requires all people who have been to the market and their close contacts not to leave home for two weeks to facilitate medical supervision.

Several local officials, including the vice-chairman of Fengtai District, were dismissed after the outbreak.

This is not the first time the disease has reappeared in China.

Before the outbreak, Beijing had recorded only 420 cases and 9 deaths, compared with over 80,000 nationwide and more than 4,600 deaths.

Like many other parts of the country, life in Beijing is on track to return to normal as businesses and schools begin to reopen.

The new outbreak in Beijing will be an important test of China's strategy to contain Covid-19, experts said.

Ho Tich Tien, chief editor of the Global Times, stated on Twitter that Beijing will not become the second Wuhan.

"It is never going to happen that Beijing will become Wuhan 2.0. The world will see Beijing's great ability to control disease, including its strong leadership, respect for science,

The Beijing authorities are still trying to track down the source of the infection, and have said they will "conduct the most rigorous epidemiological investigations".

Zhang Yuxi, manager of the Tan Phat Dia market, on June 12, told Beijing News that the virus was detected on a cutting board of an imported salmon store, raising fears of a wider risk of infection.

While investigations are ongoing, a researcher at the Beijing Center for Disease Control and Prevention said that based on the results of gene sequencing, the virus discovered at the Tan Phat Geology market was similar to strains.

"But it is not clear where the virus came from. It could come from meat or seafood or spread through the excretions of people who have come to the market," researcher Yang Peng said on China Central Television.
