1. The U.S.-China trade war has cooled, at least for now.

President Trump and President Xi Jinping of China agreed to resume trade talks, averting for now an escalation of their multibillion-dollar tariff war.

At the G20 summit meeting in Osaka, Japan, Mr. Trump on Saturday promised to hold off on any new tariffs, and he agreed to lift some restrictions on Huawei, the Chinese technology giant at the center of a dispute between the nations. Here’s what else happened at the summit.

On Sunday, Mr. Trump became the first sitting American commander in chief to set foot in North Korea as he greeted Kim Jong-un, the country’s leader, at the Demilitarized Zone. The two agreed to send their negotiators back to the table to seek a long-elusive nuclear agreement.
