A Chinese-owned company bought an obscure chip factory in Britain last year. After Washington made it clear it opposed the purchase, the U.K. initiated a probe that could unwind the deal.
Last week, U.K. Business Secretary Kwasi Kwarteng triggered a national-security review of the deal, in which a Dutch subsidiary of a Chinese chip maker bought a semiconductor factory in Wales last July. Behind the scenes, a diplomat from the U.S. Embassy in London told British officials in recent weeks that the factory—if back in British hands—could help the U.K. become a hub for making chips crucial to electric vehicles, according to people familiar with the conversations.
