BEIJING: China on Monday said tweets by President Donald Trump suggesting Beijing was involved in a massive cyberattack on the US government were "a farce" concocted for political motives.

A large-scale hack of US government agencies including the Treasury was "under control" as of Saturday, according to the outgoing US President. But in a tweet thread he undercut his own administration's assessment that Russia was behind the cyberattack, instead saying China "may" also have been involved, without providing any evidence. Chinese foreign ministry spokesman Wang Wenbin stopped short of directly denying Beijing's involvement, but called US accusations of cyberattacks "not serious, and self-contradictory." "The accusations made by the US against China have always been a farce, out of political motives," Wang told a press briefing. "The US has politicised cybersecurity issues, continuously spread false information without conclusive evidence... in an attempt to destroy China's image and mislead the international community," he added.

In July, two Chinese nationals were indicted by the US for seeking to steal coronavirus vaccine research and hacking hundreds of companies - prompting Beijing to accuse Washington of "slander". Trump's tweets on Saturday contradicted comments just a day earlier from his Secretary of State Mike Pompeo about the source and the severity of the cyberattack, leaving administration spokespeople scrambling to reconcile the conflicting takes.
