Cnn Talk With Max Foster

U.S. President Donald Trump's agenda when he touches down in Osaka, Japan on Thursday for a meeting of world leaders at this year's G20 summit will be dominated by trade wars, and the prospect of actual war. Trump's long-awaited trade talks with his Chinese counterpart Xi Jinping are set for Saturday. A tense situation in the Middle East grows ever more so as Trump plans to huddle with peers from Russia, Saudi Arabia and Germany. And stalled diplomacy with North Korea will be tested as South Korean officials say they are preparing for the President to visit the Demilitarized Zone.
