LONDON, (Reuters) -- British Prime Minister Boris Johnson toughened his rhetoric on China's Huawei on Tuesday, cautioning Beijing that he would protect critical infrastructure from "hostile state vendors" as he expressed deep concern over a new security law for Hong Kong.
Johnson, who in January allowed Huawei a limited role in Britain's 5G network, has faced intense pressure from the United States and some British lawmakers to ban the telecommunications equipment maker on security grounds.
