UPDATE 1-Chinese envoy to Canada warns against any future Huawei 5G ban

China's envoy to Canada on Thursday warned Ottawa of possible repercussions if it banned technology firm Huawei Technologies Co Ltd from supplying equipment to Canadian 5G networks, the latest blast in a deepening bilateral dispute.

Ambassador Lu Shaye, speaking at a news conference, did not give details. Canada is currently studying the security implications of 5G networks, but unlike some allies has not announced a ban on Huawei equipment.

On Wednesday, a bipartisan group of U.S. lawmakers introduced bills that would ban the sale of U.S. chips or other components to Huawei, ZTE Corp or other Chinese firms that violate U.S. sanctions or export control laws.

The bills specifically cite ZTE and Huawei, both of which are viewed with suspicion in the United States because of fears that their switches and other gear could be used to spy on Americans. Huawei is the world's biggest telecommunications equipment maker.
