G20 chair calls for unity and an end to war

STORY: "We have no other option, collaboration is needed to save the world," Indonesian President Joko Widodo said in opening remarks, before the leaders of the world's wealthiest nations began closed-door discussions.

"G20 must be the catalyst for inclusive economic recovery. We should not divide the world into parts. We must not allow the world to fall into another cold war."

The G20, which includes countries ranging from Brazil to India, Saudi Arabia and Germany, accounts for more than 80% of the world's gross domestic product, 75% of international trade and 60% of its population.
