On Wednesday, the US media outlet Vice cited a US State Department official as saying that the test was given in error and that China would stop using the swabs for testing diplomats.
The Chinese foreign ministry denied that US diplomats were asked to take anal swabs for COVID-19.
“To my knowledge … China has never required US diplomatic staff stationed in China to conduct anal swab tests,” Chinese foreign ministry spokesman Zhao Lijian said.
Earlier it was reported that some Chinese cities use anal swab tests to detect potential COVID-19 infections.
China had launched a coronavirus vaccination campaign on 15 December.
