Top officials from Britain, the United States and Canada walked out on Russia's representatives at a Group of 20 meeting on Wednesday and many members condemned Moscow's war in Ukraine, exposing deep divisions in the bloc of major economies.

Indonesian Finance Minister Sri Mulyani Indrawati, who chaired the meeting of G20 finance officials in Washington, acknowledged the body faced unprecedented challenges but called for cooperation to overcome headwinds slowing global growth.

"This is an extraordinary situation," Indrawati told reporters after the daylong meeting. "It's not business as usual, a very dynamic and challenging one."
