The Wall Street Journal reports that the Trump administration is examining whether to require that next-generation 5G cellular equipment used in the U.S. be designed and manufactured outside China, according to people familiar with the matter. The move could reshape global manufacturing and further fan tensions between the countries. A White House executive order last month to restrict some foreign-made networking gear and services due to cybersecurity concerns started a 150-day review of the U.S. telecommunications supply chain. As part of that review, U.S. officials are asking telecom-equipment manufacturers whether they can make and develop U.S.-bound hardware, which includes cellular-tower electronics as well as routers and switches, and software outside of China, the people said. The conversations are in early and informal stages, they said. The executive order calls for a list of proposed rules and regulations by the 150-day deadline, in October; so, any proposals may take months or years to adopt. The proposals could force the biggest companies that sell equipment to U.S. wireless carriers, Finland's Nokia Corp. NOK -0.19% and Sweden's Ericsson ERIC -0.70% AB, to move major operations out of China to service the U.S.
