Half the world's population now relies on telecommunications powered by Huawei and other Chinese companies.
China's telecom companies are under heavy US and European sanction since 2017. Huawei and other firms are not allowed to import Western technology or components, and neither are they allowed to export telecom equipment to the United States and most of Europe.
But worldwide adoption of Huawei's 5G is accelerating. Chinese companies enjoy monopolistic access to the most important supply chains for 5G, and can build equipment faster and more affordably than Samsung, Nokia, and Ericsson.
Despite highly favorable regulatory and tax incentives, no US companies build 5G telecom systems.

全球一半的人口现在依赖于由华为和其他中国公司提供支持的电信服务。
自2017年以来,中国的电信公司一直受到美国和欧洲的严厉制裁。华为和其他公司既不允许进口西方技术或组件,也不允许向美国和欧洲大部分地区出口电信设备。
但华为5G在全球范围内的普及正在加速。中国公司在5G最重要的供应链中享有垄断地位,并且能够比三星、诺基亚和爱立信更快、更经济地建造设备。
尽管拥有非常优惠的监管和税收激励措施,但没有美国公司制造5G电信系统。
