Briefing of diplomats comes ahead of expected release of WHO study

BEIJING — Chinese officials briefed diplomats Friday on the research into the origin of COVID-19, ahead of the expected release of a report from the World Health Organization.

The briefing appeared to be an attempt by China to get out its view on the report, which has become enmeshed in a diplomatic spat. The U.S. and others have raised questions about Chinese influence and the independence of the findings, and China has accused critics of politicizing a scientific study.

“Our purpose is to show our openness and transparency,” said Yang Tao, a Foreign Ministry official. “China fought the epidemic in a transparent manner and has nothing to hide.”

The report, which has been delayed, is based on a visit this year by a WHO team of international experts to Wuhan, the city in central China where infections from a new coronavirus were first reported in late 2019.

The experts worked with Chinese counterparts, and both sides have to agree on the final report. It’s unclear when it will come out.

Feng Zijian, a Chinese team member and the deputy director of China’s Center for Disease Control and Prevention, said the experts examined four possible ways the virus got to Wuhan.

They are a bat carrying the virus infected a human, a bat infected an intermediate mammal that spread it to a human, shipments of cold or frozen food, and a laboratory that researches viruses in Wuhan.

The experts voted on the hypotheses after in-depth discussion and concluded one of the two animal routes or the cold chain was most likely how it was transmitted. A lab leak was viewed as extremely unlikely, Feng said.

His remarks were reported by state broadcaster CCTV, which said envoys from 50 countries and the League of Arab States and the African Union attended the briefing at the Foreign Ministry.

“China firmly opposes certain countries’ attempts to politicize the origin tracing issue and make groundless accusations and hold China accountable,” the ministry said in an online post about the briefing.

Separately, Foreign Ministry spokesperson Hua Chunying said, “I would like to stress that virus tracing is a scientific issue that should be studied by scientists through cooperation.”

She told reporters that the experts are still discussing the contents and translation of the report, and she did not know when it would be released.
