BUENOS AIRES (Reuters) - Chinese President Xi Jinping and the leaders of major developing economies condemned protectionism at a G20 summit in Argentina on Friday overshadowed by U.S. President Donald Trump's threat to escalate tariffs on China.

This year's two-day gathering is a major test for the Group of 20 industrialized nations, whose leaders first met in 2008 to help rescue the global economy from the worst financial crisis in seven decades.
