US intelligence finding shows China surging equipment sales to Russia to help war effort in Ukraine

China has surged sales to Russia of machine tools, microelectronics and other technology that Moscow in turn is using to produce missiles, tanks, aircraft and other weaponry for use in its war against Ukraine, according to a U.S. assessment.

Two senior Biden administration officials, who discussed the sensitive findings Friday on the condition of anonymity, said that in 2023 about 90% of Russia’s microelectronics came from China, which Russia has used to make missiles, tanks and aircraft. Nearly 70% of Russia’s approximately $900 million in machine tool imports in the last quarter of 2023 came from China.

Chinese and Russian entities have also been working to jointly produce unmanned aerial vehicles inside Russia, and Chinse companies are likely providing Russia with nitrocellulose needed to make propellants weapons, the officials said.

Beijing is also working with Russia to improve its satellite and other space-based capabilities for use in Ukraine, a development the officials say could in the longer term increase the threat Russia poses across Europe. The officials, citing downgraded intelligence findings, said the U.S. has also determined that China is providing imagery to Russia for its war on Ukraine.

The officials discussed the findings as Secretary of State Antony Blinken is expected to travel to China this month for talks. President Joe Biden has previously raised his concerns directly with Chinese President Xi Jinping about Beijing indirectly supporting Russia's war effort.

While China has not provided direct lethal military support for Russia, it has backed it diplomatically in blaming the West for provoking Russian President Vladimir Putin’s decision to launch the war and refrained from calling it an invasion
