Windows of a German department store are covered with wooden boards before the upcoming G20 summit in Hamburg, Germany, July 7-8. The G20 summit on July 7-8 comes amid tensions over trade, climate, and refugee policy and increased uncertainty over the U.S. commitment to multilateral institutions. The annual summit of the Group of Twenty (G20), a gathering of the world's largest economies, has evolved into a major forum for discussing the most pressing global issues. One of the group's most impressive achievements was its robust response to the 2008 global financial crisis, but some analysts say its cohesion has since frayed. The July 2017 summit in Hamburg, Germany, is the first for U.S. President Donald Trump, who has already clashed with many of the group's members over trade, climate, and refugee policy.
