The UK media regulator has revoked a Chinese TV licence after it concluded that the Chinese Communist Party had ultimate editorial responsibility for the channel while officials in Beijing lodged a formal complaint over the BBC's COVID-19 coverage.
UK and Chinese officials have been exchanging barbs for months over the crackdown in Hong Kong, concerns over the security of Huawei technology and the treatment of Uighur Muslims in China's remote Xinjiang region.
After an investigation, the British regulator Ofcom concluded that China Global Television Network's (CGTN), an English language international Chinese channel, was ultimately controlled by the Communist Party.
"Our investigation showed that the licence for China Global Television Network is held by an entity which has no editorial control over its programs," Ofcom said.
"We are unable to approve the application to transfer the licence to China Global Television Network Corporation because it is ultimately controlled by the Chinese Communist Party, which is not permitted under UK broadcasting law."
Within minutes of the Ofcom statement, China said it had lodged "stern representations" to the British Broadcasting Corp over what it said was "fake news" coverage of COVID-19 and urged the broadcaster to publicly apologise.
China's foreign ministry complained about coverage broadcast on January 29 about the coronavirus, saying that the BBC had recently "linked the pandemic to politics" and "rehashed theories about covering up by China".
It said the BBC used a clip to say the Chinese virus prevention department had used violence to enforce the law when it was actually a clip about an anti-terrorism exercise.
"China urges the BBC Beijing bureau to take China's position seriously," the ministry said.
The BBC, it said, should "stop harbouring ideological bias, stop smearing China, uphold professional ethics, and do objective, fair reporting on China".
The BBC said on Thursday it rejected the accusations.
"We stand by our accurate and fair reporting of events in China and totally reject these unfounded accusations of fake news or ideological bias," it said in a statement.
It added that the BBC reports without "fear or favour".
