One down, still others to go. President Donald Trump claimed a victory after Washington and Mexico agreed on measures to stem the flow of Central American migrants into the United States.

Trump called off plans to impose a 5% tax on Mexican exports, and Treasury Secretary Steven Mnuchin, speaking to reporters Saturday in Fukuoka on the sidelines of a meeting of financial leaders of the Group of 20 major economies, urged China to follow suit and return to stalled negotiations.

Mnuchin said he planned to have a private conversation with the head of China's central bank, Yi Gang. In a G-20 group meeting, the two were seen exchanging friendly remarks, but there were no fresh signs Beijing is ready to compromise in the dispute over trade and technology.
