What's wrong with Huawei, and why are countries banning the Chinese telecommunications firm?
Intelligence officials in many countries are concerned the company could be helping the Chinese government spy on companies, military units and government agencies.
No Chinese company is fully independent of its government, which reserves the right to require companies to assist with intelligence gathering. Huawei is even more closely tied to the government than many Chinese firms: Its founder, Ren Zhengfei, is a former technologist in the Peopleâ€™s Liberation Army. As his company grew, so did international concerns about whether Huawei equipment could be used to spy on companies and governments around the world.
