World leaders in Hamburg for two-day gathering

World leaders gather in the German city of Hamburg for the two-day G20 Summit. The theme of this year's summit is "Shaping an Inter-connected World". With the US becoming more isolated under Donald Trump, will this G20 Summit witness reorganization in a multipolar world? We turn to our panel to find out: Yuan Peng, vice president of the China Institutes of Contemporary International Relations; Axel Berger, head of the G20 Policy Research Group of the German Development Institute; Adam Posen, president of the Peterson Institute; Daniel Gros, director of the Center for European Policy Studies.
