China and Russia denounced a US report on national security strategy. President Donald Trump?s first National Security Strategy pillories China and Russia as "revisionist powers" bent on rolling back American interests, according to the hard-hitting text released Monday.

The document -- designed to serve as a framework for the Trump administration?s approach to the world -- uses remarkably biting language to frame Beijing and Moscow as global competitors.

The Kremlin denounced the ?imperialist character? of the report, accusing Washington of clinging to a ?unipolar world.?

"The imperialist character of this document is obvious, as is the refusal to renounce a unipolar world, an insistent refusal," Kremlin spokesman Dmitry Peskov told reporters, adding the Russian authorities "cannot accept that the country is treated as a threat to the security of the United States".

China said Washington should "abandon outdated notions such as a Cold War mentality".

"Any country, or any report, which distorts the facts, or maliciously slanders will only do so in vain," foreign ministry spokeswoman Hua Chunying told a regular news briefing.
