US tech groups rebuff Trump’s new anti-Huawei push

US technology companies have rebuffed a Trump administration request that they pledge to stop sourcing supplies from some Chinese companies, amid concerns that such a policy could break competition laws. The state department asked telecoms carriers and chipmakers to sign up to a set of principles which would have in effect shut out Huawei, and possibly others, according to three people briefed on the proposals. The initiative, led by Keith Krach, under-secretary of state for economic growth, energy and the environment, and a former tech industry executive who oversees its Office of Global Partnerships, was aimed at securing support for what the department called a Global Digital Trust Standard.
