New Zealand’s international spy agency is preventing mobile company Spark from using Huawei products in its planned 5G upgrade, due to a “significant network security risk,” it said Wednesday. (Associated Press)

Talking point: The move follows a similar ban in Australia, where the Chinese telecommunications company was blocked from rolling out a 5G network in August, and an active campaign by the U.S., encouraging its allies to drop Huawei. Canada has an ongoing review to determine any risks posed by the company, and Ottawa isn’t ruling out blocking the products. China is New Zealand’s largest trading partner; the move could have diplomatic and economic implications for the country, which is also part of the “Five Eyes” security alliance with the U.S., the U.K., Canada and Australia.
