Can the G20 end trade wars and political infighting ?

Leaders of the world's wealthiest economies are in Japan to discuss the biggest challenges to global free trade.

The group of 20 summit, or G20, has been held every year for the past two decades.

This year's summit in Osaka is supposed to unite leaders around issues such as free trade and climate change.

But political tensions and the trade war between the U.S. and China are creating divisions.

Can the participants find consensus? And how relevent is this meeting for the rest of the world?
