China urges cooperation after US brands it a competitor
"On the basis of mutual respect, China is willing to exist peacefully with other countries including the United States. But the US ought to adapt to and accept China's development," it said.
In a new national security strategy based on US President Donald Trump's "America First" vision on Monday, the United States lumped China and Russia together as competitors seeking to erode US security and prosperity.
The singling out of China and Russia as "revisionist powers" also comes despite Trump's own attempts to build strong relations with Chinese President Xi Jinping as the two sides seek to rein in North Korea's nuclear and missile programmes.
A senior US administration official said Russia and China were attempting to revise the global status quo - Russia in Europe with its military incursions into Ukraine and Georgia, and China in Asia by its aggression in the South China Sea. Russia denies the allegations that it meddled with the 2016 US presidential election.
China says its expansion of South China Sea islets is for peaceful purposes only.
The US administration also warned that intellectual property theft by China is a national security problem.
