China's Huawei has responded again to actions from the Federal Communications Commission, releasing an ex parte memo further laying out its response to the commission's efforts to block its equipment on national security grounds.

"While Huawei does not agree with the view that Chinese companies pose a threat simply because they are Chinese, Huawei agrees that threats to network security do exist, and should be addressed comprehensively trough a holistic approach to supply chain security, not through a vendor-to-vendor approach," according to the brief.

The company cites comments by government officials that it says appear to indicate the U.S. may have economic motives for the ban, and cites the use of its equipment in other European and North American markets.
