The high-tech rivalry between the United States and China is getting ugly. So far in 2018, the Trump administration has blocked high-tech acquisitions by Chinese firms, complained about Chinese technology licensing practices at the World Trade Organization and threatened tariffs on Chinese high-tech imports.The administration has also banned US companies from selling parts to Chinese phone maker ZTE, though the President has promised to revisit this decision. For its part, China has brandished its own tariffs while also making promises to protect foreign intellectual property and further open the Chinese economy. Bilateral talks remain underway.
