President Trump said Monday he would meet with presidents Vladimir Putin of Russia and Xi Jinping of China at the G20 summit in Japan this June.

“We’re going to be meeting, as you know, at the G20 in Japan. And that’ll be, I think, probably a very fruitful meeting,” Trump said of XI during a White House appearance with Hungarian Prime Minister Viktor Orban.

The announcement came as the world’s two largest economies are locked in an escalating trade war.
