Alibaba's Ma calls US-China trade war 'stupidest thing in the world'

The US-China trade war is the "stupidest thing in the world," Alibaba e-commerce tycoon Jack Ma said. "Trade is to form ... peace. Trade is to communicate...nobody can stop free trade," he said. Ma also delivered a veiled rebuke to Trumpism, decrying "protectionism", "isolationism" and "the law of the jungle".
