The Olympic-sized event is scheduled for September in Hangzhou, near Shanghai, but China's economic capital is facing a major covid crisis.
"No official decision has been taken by the committee for the time being, but there is a possibility that they will be postponed," said Kuwaiti Husain Al-Musallam, director general of the Olympic Council of Asia, organizer of the Games.
Many international sporting events have already taken place in China since the start of the pandemic, in particular the Winter Olympics organized by Beijing in a health bubble in February.
But Shanghai, the most populous Chinese city, is suffering the most terrible episode of the Covid epidemic for two years in China, with long weeks of restrictions which confine the majority of its 25 million inhabitants to their homes.
All 56 venues for the Asian Games have already been completed, Chinese organizers said in April, while promising to release a plan to control the virus that will be modeled on that of the Winter Olympics.
"We are making some final adjustments and improvements to the facilities," Lu Chunjiang, an operations official at the Hangzhou Olympic Sports Center, was quoted by state broadcaster CCTV as saying.
Hangzhou, located less than 200 kilometers from Shanghai, is to host the Asian Games from September 10 to 25, and become the third Chinese host city, after Beijing in 1990 and Guangzhou in 2010.
