Huawei also suffers frustrations and political obstacles in some other developed countries, but the US has the most distrust.
A world-leading position in technology has long supported US hegemony, so it may not be that surprising that given US protectionism for its domestic enterprises it has tricky trade relations with China.
There are actually many ways to disperse security fears over Huawei. It's said that part of the reason why the UK trusts Huawei more than the US is that all software and equipment from Huawei is tested by a shared Cyber Security Evaluation Centre before entering the UK.
The US has long criticized Huawei for opacity in terms of business information. Huawei could move toward transparency to expel these suspicions. The Chinese enterprise could also enhance its PR abilities and put more emphasis on developing public relations and increasing communications with media and local communities to convince local users that fair trade can benefit them.
Full competition brings the maximum benefits to the market and the consumer, thus fostering competition is a key part of US business regulations. But clearly, it doesn't follow this rule when it comes to facing a robust rival from other countries.
