"I must say, enough is enough! You have created enough troubles for the world already,” Ambassador Zhang Jun told a Security Council meeting through video conference on Thursday.
"Regrettably, we have once again heard noises from the US that are so at odds with the atmosphere of the meeting,” he said.
Zhang made the remarks two days after President Donald Trump used much of his pre-recorded video address to the General Assembly to accuse China of withholding information about the coronavirus pandemic.
Trump said on Tuesday that Beijing allowed the coronavirus to "leave China and infect the world.”
