US warns use of untrusted tech could limit data-sharing with allies

The US Embassy in Berlin said on Monday that use of untrusted vendors by allies in their 5G mobile networks could jeopardize future sharing of intelligence by the US government.

An embassy spokesman declined to comment specifically on a Wall Street Journal report about the US government’s first explicit warning to Germany of consequences if China’s Huawei Technologies Co. gets a role in Germany’s next-generation mobile infrastructure.
