The SAR government says it strongly opposes the sending of a letter by the United States Congressional-Executive Commission on China to the UK prime minister, Rishi Sunak, saying it interferes in judicial proceedings with regard to a court case involving jailed media tycoon Jimmy Lai, who faces national security charges.

It also 'vehemently condemned' attempts by some US politicians to get sanctions imposed on judicial officers and prosecutors, saying this could amount to contempt of court or perverting the course of justice.

"The US politicians' arbitrary and unreasonable bullying act has seriously violated international norms and grossly interfered in Hong Kong affairs and China's internal affairs at large. It is a blatant attempt to undermine the rule of law of Hong Kong and will only expose their own weakness and be doomed to fail," a government spokesman said.
