Ugh. Note that this is a capitulation. China's retaliatory import tariff rate remains in effect, and they get to decide which industries to relax, if any. The net effect is that if you're in one of the handful of businesses that export to China, the Trump administration threw you under the proverbial bus.
While we're at it, China might as well impose a 145% export tax on phones, computers and chips, just to taunt.
