China said the U.S. “inappropriately overreacted” to the deadly virus that originated there and hasn’t provided much help to counter the outbreak, disputing the Trump administration’s claim that it offered assistance.

“The U.S. government hasn’t provided any substantial assistance to us, but it was the first to evacuate personnel from its consulate in Wuhan, the first to suggest partial withdrawal of its embassy staff, and the first to impose a travel ban on Chinese travelers,” Chinese foreign ministry spokeswoman Hua Chunying told reporters on Monday.

The U.S. has offered its top public health experts to help China with the coronavirus outbreak but so far Beijing hasn’t responded, National Security Adviser Robert O’Brien said Sunday.
