With the outlook of the global economy clouded by the ongoing U.S.-China trade war, finance leaders from the Group of 20 nations kicked off a two-day meeting Saturday in Fukuoka to discuss measures to guard against economic risks.

The meeting came as U.S. President Donald Trump announced that he was calling off planned tariffs on imports from Mexico after reaching a deal on migration, a decision that was welcomed by Bank of Japan Gov. Haruhiko Kuroda.

Still, trade friction is an unpredictable factor that might drag down growth, although the global economy will likely regain momentum in the second half of the year, Kuroda told reporters.
