China on Wednesday demanded Washington stop ``oppressing Chinese companies'' after U.S. regulators declared telecom equipment suppliers Huawei and ZTE to be national security threats.

In a statement Saturday, Huawei urged the FCC to reconsider what it called a “profoundly mistaken” and “unlawful order.”

Harper told Fox that Chinese tech giants Huawei and ZTE are tightly tied to the Chinese security apparatus, "and we think there are some real serious issues there."

The Pentagon banned the sale of  Huawei and ZTE phones on military bases on Wednesday and while the devices are not sold on Canadian bases, federal officials are saying little about whether they share American fears the devices could be used to spy on soldiers.
