BEIJING — Two months since China’s latest Covid outbreak began, many businesses in the country’s two largest cities by GDP face new or existing constraints on operations.

Over the weekend, the capital city of Beijing closed theme parks and banned dining in restaurants to control Covid — just as a five-day holiday got underway. During the holiday last year,Official figures show that domestic tourism revenues increased by more than two-thirds in 2017 compared to the previous year.

Universal Beijing Resort is closed from Sunday to further notice. The holiday officially ends Wednesday and will be observed by all indoor sporting facilities, including internet cafés, gyms, live performances, and entertainment venues.

However, Shanghai showed signs of loosening restrictions in the past few days, despite being subject to some of the strictest citywide lockdowns.

Saturday’s announcement by the city included 1,188 additional companies to its whitelist, which allows for the resuming of production. For the initial list announced in mid-April of 666 companies — including 247 foreign-funded ones — more than 80% had resumed work, the city said.

The EU Chamber of Commerce in China stated that the whitelist was a “promising sign” for Shanghai’s rebound.

However, truck driver shortages, and the difficulty of getting workers from factory bubbles to their homes, remained challenges, according to Bettina Schoen Behanzin, vice president of the chamber and Shanghai chair. Friday’s estimate by Bettina Schoen-Behanzin was that logistics and supply chain problems will continue through June.

According to official statistics, Monday’s Shanghai population was 2.5 million. This is down from the 5.3 million who were subject to strict stay-home orders four days ago. Municipal authorities declared that six parts of Shanghai have been cured of the virus, although not all of Shanghai’s downtown area.

According to the city, it is building sites to conduct regular virus testing.

On Monday, China’s mainland reported a decrease in Covid symptoms. It was 368, compared to close to 1000 in the past weeks. Shanghai had 274 cases of symptoms while Beijing reported 51 cases.

Residents are restricted from leaving certain areas of the city, but businesses located in the rest of the city remain accessible to anyone who has received a negative viral test within the past 48 hours.

Beijing has conducted mass testing for multiple times in the week. The government also stated that weekly testing would be necessary after holidays to use public transportation or to go to public places like supermarkets.

The city opened a 1,200-bed centralized quarantine unit on Sunday.
