US Treasury Secretary Janet Yellen does not rule out sanctions against Chinese banks if they are found to have carried out transactions in connection with the Russian war effort in Ukraine. „I absolutely would not rule out the possibility we would sanction an individual bank if we had the necessary level of … evidence to be able to put sanctions on,“ Yellen told the Reuters news agency on Friday. She said warnings to larger Chinese banks have been successful, making them „very wary“ of sanctions that would cut them off from dollar-based transactions. „Authorities in China recognize that our use of these sanctions would be a serious threat with very adverse consequences,“ Yellen said. „They want to trade with Russia, but they do not want their banks sanctioned.“
