Even if it’s just bluster, the damage is already done. China’s financial elites now see the U.S. shifting the front of its trade war to financial markets – in part because its campaigns on the tariff and technology fronts haven’t been going so well. One reason is that China is still a heavily managed economy. Whereas President Donald Trump has to wait for higher tariffs to seep into consumers’ budgets before he can steer their behaviors, Beijing can simply tell its state-owned enterprises, such as Cofco Corp., to stop buying U.S. soybeans. That snaps the backbone of American farmers – Trump’s key supporters – a lot more quickly than any pain Trump can inflict in reverse. As for blocking semiconductor exports to China, that hasn’t gone according to plan either. Anticipating supply shortages, Huawei Technologies Co. had been stockpiling materials for months, and is now making its own chips.
