President Joe Biden’s naive diplomatic strategy concerning Russia has been mocked following reports that he shared intel with communist China for months in order to avert the Russian invasion of Ukraine, only to have the Chinese turn that intel over to Russia.

“Over three months, senior Biden administration officials held half a dozen urgent meetings with top Chinese officials in which the Americans presented intelligence showing Russia’s troop buildup around Ukraine and beseeched the Chinese to tell Russia not to invade,” the New York Times reported on Friday.

“Each time, the Chinese officials, including the foreign minister and the ambassador to the United States, rebuffed the Americans, saying they did not think an invasion was in the works. After one diplomatic exchange in December, U.S. officials got intelligence showing Beijing had shared the information with Moscow, telling the Russians that the United States was trying to sow discord — and that China would not try to impede Russian plans and actions,” unnamed U.S. officials reportedly told the media outlet.

Biden’s outreach to China appears to have begun after a video summit that was held between the president and Chinese President Xi Jinping on Nov. 15.
