The Group of 20 finance chiefs vowed Sunday to use "all policy tools" to pursue growth as Britain's decision last month to leave the European Union adds to the uncertainty in the global economy amid terrorism and other challenges.

Finance ministers and central bank chiefs from G-20 major economies, including Finance Minister Taro Aso and Bank of Japan Gov. Haruhiko Kuroda, condemned recent terrorist attacks "in the strongest possible terms" and agreed to contain all forms of terrorism financing, according to a communique released after the meeting in southwest China.

On the exchange market, the G-20 reaffirmed previous commitments to refrain from competitive devaluations, while reiterating that excess volatility and disorderly moves in exchange rates can have adverse effects for economic and financial stability.
