Finance chiefs from the Group of 20 major economies on Thursday shared concerns about growing downside risks to an otherwise stable global economy.

Summing up discussions among G20 finance ministers and senior officials over dinner in Buenos Aires, Finance Minister Taro Aso said, "The world economy is basically stable, but there are many uncertainties in the outlook, an example of which is (the slowdown of) China."

Speaking to reporters after the meeting, Aso said the G20 officials did not specifically touch on simmering trade tensions between Washington and Beijing, partly because U.S. Treasury Secretary Steven Mnuchin was absent from the meeting.
