BEIJING (REUTERS) - China's foreign ministry said on Monday (Nov 2) it will take all necessary measures to protect Chinese journalists in response to the United States delaying visa renewals for Chinese reporters.

China urges the United States to stop its "political crackdown" on Chinese journalists, ministry spokesman Wang Wenbin said at a news briefing.

"Upholding the principle of answering words with words and actions with actions, China will take all necessary measures to safeguard the legitimate rights and interests of Chinese journalists," said Mr Wang.

The United States in March slashed the number of Chinese nationals allowed to work at the US offices of major Chinese state-owned media, and on May 11 limited their stay to 90 days, with an option to extend.

China has expelled US journalists working for several US newspapers this year, and introduced new visa restrictions on several US media companies.

Some Chinese journalists were last week granted visa extensions due to expire as soon as Nov 4, said Mr Wang. Others have not been granted an extension yet, he said.

"We once again urge the US to immediately give up its illusions and stop the political persecution and suppression of Chinese reporters," said Mr Wang.

"Do not say that you were not forewarned by China."

The two countries' relations have deteriorated recently over various issues including trade and the novel coronavirus outbreak, which originated in China.
