Russia asks China for military support, US official says
Russia has asked China for military support and other aid in the time since it invaded Ukraine on Feb. 24, a senior U.S. official told ABC News.
China and Russia recently strengthened their partnership, and Chinese President Xi Jinping has stood by Russian President Vladimir Putin as he's bombarded Ukraine.
On Sunday, President Joe Biden’s top national security adviser, Jake Sullivan, said during an interview with CNN that the U.S. was "watching closely to see the extent to which China actually does provide any form of support, material support or economic support, to Russia."
"It is a concern of ours," Sullivan said, adding that the U.S. has communicated to Beijing that it will "not stand by and allow any country to compensate Russia for its losses from the economic sanctions."
Sullivan is planning to meet a top Chinese official in Rome on Monday.
The Financial Times, The Washington Post and The New York Times first reported on this development.
