BEIJING (AP) China on Wednesday called comments by President Joe Biden referring to Chinese leader Xi Jinping as a dictator extremely absurd and irresponsible.

The new clash of words comes just over a day after Secretary of State Antony Blinken concluded a visit to Beijing that sought to break the ice in a relationship that has hit a historical low.

Foreign Ministry spokesperson Mao Ning said Bidens comments at a fundraiser in California go totally against facts and seriously violate diplomatic protocol, and severely infringe on Chinas political dignity.

It is a blatant political provocation. China expresses strong dissatisfaction and opposition, Mao said at a daily briefing.

The U.S. remarks are extremely absurd and irresponsible, Mao said.

Blinkens visit, during which he met with Xi, was aimed at easing tensions between the two superpowers but appeared not to have achieved any solid results.

Biden, at the fundraiser on Tuesday night local time, said that Xi was embarrassed over the recent tensions surrounding a suspected Chinese spy balloon that had been shot down by the Air Force over the East Coast.

Thats a great embarrassment for dictators. When they didnt know what happened, Biden said.

Mao reiterated Chinas contention that the balloon was intended for meteorological research and had been blown off course accidentally.

The U.S. should have handled it in a calm and professional manner, she said. However, the U.S. distorted facts and used forces to hype up the incident, fully revealing its nature of bullying and hegemony.
