Bloombergs wrote that the U.S.-China tech cold war is about to spread, and that will force leaders to make some difficult decisions..U.S. technology still leads the world, and it'll stay that way for a while. But China has shown a willingness to engage and help developing nations in ways the U.S. once did...Numerous developing nations want high-speed rail lines, efficient ports and airports, and energy-saving, low-pollutant electric vehicles. Each of these could be provided by America or its allies. Japan, Europe and Canada have the technology and skill to help. But in addition to being capable of offering those items, China has the political and fiscal capital to do so. The will already exists in the form of its Belt and Road Initiative...But if a nation agrees to install Chinese networks or infrastructure, there's an increasing chance it will be cut off from U.S. products under the guise of American national security..Just as the world was divided along military lines 70 years ago, the digital Iron Curtain will force political leaders to decide whether they're Team China or Team America.
