For the first time, a Chinese company—Huawei—is set to lead the global transition from one key national security infrastructure technology to the next.

The Huawei case study is in some ways the canary in the coal mine for emerging technologies and an illustration of what can happen to U.S. competitiveness when China’s companies do not have to base decisions on market forces.
