WARSAW—An espionage trial involving a former Polish secret services agent and an ex-employee of Huawei begins in a Warsaw court on Tuesday as some European states consider whether to exclude the Chinese group’s equipment from their 5G telecom networks.
Poland arrested the two men in January 2019 on suspicion of spying for China, in a move that has ramped up international debate over the potential security risks of using Huawei equipment in communications networks.
