Treasury's Yellen asked China to 'crack down' on Chinese firms aiding Russia

U.S. Treasury Secretary Janet Yellen on Friday said the U.S. government had seen evidence that Chinese firms may be aiding in the flow of equipment to Russia despite Western sanctions, and said she urged China to crack down such actions.

Yellen said she raised the issue during two days of meetings with Chinese Vice Premier He Lifeng, expressing concern that equipment "helpful to Russia's military" was evading sanctions.
