US President Donald Trump has agreed to include a pledge to fight trade protectionism in a final communique due to be released later on Saturday at the end of a summit of Group of Seven leaders, a G7 source said.

Trump has previously endorsed protectionist measures, saying the United States was suffering due to unfair trade practices from some of its main Western allies, including Germany, as well as from China and some developing nations.

"Trump agreed that the fight against protectionism should be in the final statement," a G7 source said.
