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.

"I believe there will be repercussions" if Huawei were to be banned, said Lu, who spoke through an interpreter. He urged Ottawa to make a "wise" decision.
