U.S. Treasury Secretary Janet Yellen said the United States was in constant discussions with its partners about further sanctions and could take "additional actions" to pressure Moscow.
At a Wall Street Journal conference, Yellen would not preview any specific actions under consideration, but stressed that further measures were likely "if Russia continues this war against Ukraine."
Biden told reporters, "We're always open to additional sanctions" when asked about U.S. plans after the European Union proposed its toughest sanctions yet against Russia, including a phased oil embargo.
"I'll be speaking with the members of the G7 this week about what we're going to do or not do," Biden added.
