Finance chiefs of the world's 20 leading economies are expected to vow further cooperation this weekend to ensure economic and market stability after Britain voted to leave the European Union last month.

At a two-day meeting starting Saturday in the Chinese city of Chengdu, the Group of 20 finance chiefs are expected to put "all policy tools" on the table to prevent adverse effects from Brexit from spreading as the global economic recovery remains subdued.

Discussions are likely to focus on Brexit's effects on the global economy and market, with the International Monetary Fund already projecting slower growth for 2016 and 2017.
