U.S president Joe Biden calling Chinese president a "dictator" seriously violated China's political dignity and amounted to public political provocation, China's foreign ministry said on Wednesday.
China expressed strong dissatisfaction and firm opposition, ministry spokesperson Mao Ning said at the regular news conference.
"The relevant remarks by the US side are extremely ridiculous and irresponsible, they seriously violate basic facts, diplomatic protocol and China's political dignity," foreign ministry spokeswoman Mao Ning told a regular briefing, adding: "They are an open political provocation."
Biden made the remarks at a fundraiser in California on Tuesday, a day after U.S. Secretary of State Antony Blinken met Xi on a trip to China that was aimed at easing tensions between the two countries.
