Britain takes US concerns about its use of Huawei equipment seriously but is confident a trade deal with the United States will be among its first after leaving the European Union, its foreign secretary said on Monday. US officials have hinted future trade talks could be affected by Britain’s decision last month to grant Huawei [HWT.UL] a limited role in its 5G mobile network, frustrating a global bid by the United States to exclude the firm from the West’s next-generation communications systems. “We listened and take the concerns of our American friends very seriously,” Dominic Raab said in response to a question about the issue. “We are reasonably confident that we can do a free trade agreement (with America) in that first wave of post-Brexit trade deals,” Raab added, during a visit to Singapore. “We have had a good conversation about Huawei and the one thing we all recognise is there has been market failure in terms of high-trust vendors being able to provide telecoms infrastructure.”
