The World Bank on Wednesday forecast global economic growth for this year at 2.5 percent, down 0.2 percentage point from its estimate last June, citing weaker-than-expected trade and manufacturing activity in advanced economies amid the U.S.-China trade war.

It also projected slight growth for Japan's economy in the wake of the consumption tax hike and deadly typhoons.

In its Global Economic Prospects report, the Washington-based institution left its growth forecast for Japan unchanged at 0.7 percent.
