U.S.-CHINA TRADE TIFF: On Friday the U.S. is set to impose a 25 percent tariff on $34 billion worth of Chinese imports. And China is expected to strike back with tariffs on a similar amount of U.S. exports. The big question is how far the two countries will go in their dispute over trade. On Thursday in China, Commerce Ministry spokesman Gao Feng hit back at "threats and blackmail" ahead of the planned U.S. tariff hike. He added that China would be forced to fight back to protect its own interests.
