SAN FRANCISCO — Huawei, the Chinese technology company accused by the authorities in the United States of posing a security risk, is expanding its operations in Canada.

Huawei said on Thursday that it would hire 200 new employees in Canada — an increase of about 20 percent to the company’s work force in the country. The new hires are part of an expansion of Huawei’s research and development efforts as it works to secure a place in the development of Canada’s 5G wireless networks.

Huawei, one of the largest telecommunications technology makers in the world, is fighting to maintain its position under increasing pressure from the United States. American authorities believe that Huawei technology could allow the Chinese government to spy on countries that rely on the company’s wireless network systems.

Huawei will increase its investments in Canadian research and development by 15 percent, building on a $136 million investment it made in 2018, the company said.
