Las Vegas/Hong Kong

BEST Buy, the largest US consumer electronics retailer, will cut ties with China's Huawei Technologies, a person familiar with the matter said, amid heightened scrutiny on Chinese tech firms in the United States.

Best Buy will stop selling Huawei's devices over the next few weeks, according to the person with knowledge of the matter - a setback for the Chinese telecommunications giant as it looks to expand in the US market.

The move, after similar actions from US carriers including AT&T, comes as the country's scrutiny of Chinese tech firms grows amid simmering tensions over US-China trade and concerns of security.

A Best Buy spokesman told Reuters that the firm could not comment on specific contracts with vendors. "We make decisions to change what we sell for a variety of reasons," he said.

Huawei said in emailed comments on Thursday that it valued its relationship with Best Buy but could not discuss details of its partnership with the firm.

"Huawei currently sells its products through a range of leading consumer electronics retailers in the US," the firm said, adding its products met the "highest security, privacy and engineering standards in the industry".

Earlier this year, AT&T was forced to scrap a plan to offer Huawei handsets after some members of Congress lobbied against the idea with federal regulators, sources told Reuters. Verizon Communications also ended its plans to sell Huawei phones last year, according to media reports.

Last month two Republican Senators introduced legislation that would block the US government from buying or leasing telecommunications equipment from Huawei or Chinese peer ZTE Corp, citing concern the firms would use their access to spy on US officials.

The tougher climate in the United States has forced Huawei to sell its flagship smartphone Mate 10 Pro - its challenger to the iPhone - in the United States only through open channels. REUTERS
