How China is battling ever more intensely in world markets

IF DONALD TRUMP had slapped punitive tariffs on all Chinese exports to America, as he promised, he would have started a trade war. Fortunately, the president hesitated, partly because he wants China’s help in thwarting North Korea’s nuclear ambitions. But that is not the end of the story. Tensions over China’s industrial might now threaten the architecture of the global economy. America’s trade representative this week called China an “unprecedented” threat that cannot be tamed by existing trade rules. The European Union, worried by a spate of Chinese acquisitions, is drafting stricter rules on foreign investment. And, all the while, China’s strategy for modernising its economy is adding further strain.
