Chinese Foreign Ministry stressed Thursday that the Chinese government has been open and transparent in its fight against COVID-19, denouncing U.S. President Donald Trump's remarks that "China is on a massive disinformation campaign."

Spokesperson Zhao Lijian said China speaks with fact and reason. He added that the world clearly knows who is sparing no effort in saving lives and pushing forward global cooperation.

Later on Wednesday, the U.S. president lashed out at China over the coronavirus pandemic.

"China is on a massive disinformation campaign because they are desperate to have Sleepy Joe Biden win the presidential race," he claimed in a tweet.

Speaking at a daily briefing on Wednesday, Zhao pushed back against U.S. criticism, saying Washington had made "many mistakes" and peddled many lies and rumors.

"The U.S. has seemingly forgotten that in the past, U.S. leaders have repeatedly and publicly praised China's anti-epidemic work," Zhao said. He blamed U.S. politicians "who want to shift the blame but can't shift it away."
