China reacted to tariff exemption on consumer electronics by the US calling it a "small step".
President Donald Trump on Friday defended his tariff policy, declaring it was "doing really well" even as China escalated the trade war by raising tariffs on US goods to as high as 125 percent.
The Chinese move rattled global financial markets, triggering a sharp selloff in US government bonds, a slide in the dollar, and volatile swings in stock prices. The latest retaliatory measures from Beijing deepened investor anxiety already stoked by Trump's surprise announcement of sweeping tariffs on dozens of US trade partners the previous week.
