What Happened : The White House is mulling an order that would ban the use of any Chinese-made equipment on U.S. 5G networks, regardless of where the company is from, The Wall Street Journal reported June 23. Why It Matters : If the U.S. administration enforces the measure, European companies like Ericsson and Nokia would be forced to move their production of U.S.-bound 5G equipment to plants outside China. Additionally, any shifts in supply chains to the United States could become permanent — unlike temporary trade tariffs. Background : U.S. President Donald Trump and Chinese President Xi Jinping could reach a deal at the G-20 later this week to reduce tariffs in their trade war, yet the parallel tech war — which centers on U.S. fears that Beijing can use Chinese-built technology for espionage — is unlikely to abate in the near term.
