Book: US general called China over fears of war

A new book has claimed that the United States' top military officer secretly called his Chinese counterpart over fears that then-President Donald Trump would spark a war.

The Washington Post and other media outlets reported the revelations described in the book, written by journalists Bob Woodward and Robert Costa, which will be released next week.

General Mark Milley, the Chairman of the Joint Chiefs of Staff, reportedly first called China last October, due to concerns over Trump's provocative remarks against Beijing. He allegedly reassured China that the US would not attack. In the book's account, a second call took place in January.

The book also reported that Milley believed Trump was mentally unstable following his defeat in the presidential election last November. The general reportedly told senior US military officials that he had to be involved if Trump gave any order, including a nuclear launch.

Trump has responded by saying that he "did not ever think" of attacking China.
