Finance officials of major economies have pledged to boost sluggish global growth and promised to defend against the shockwaves of Britain's vote to leave the European Union.

In a joint statement after a two-day meeting, envoys of the Group of 20 also rejected trade protectionism, an issue that has risen in prominence as US Republication presidential candidate Donald Trump has talked about restricting access to American markets.
