Because of the tensions in relations between the United States and China, both countries regularly impose on each other different types of duties or bans. The victims of such decisions are, among others, Chinese companies which mainly create smartphones, especially we mean Huawei and ZTE. In addition, ZTE, as a result of violation of US law, has been banned from selling its equipment in the United States. After some time this penalty was canceled, but repression of Chinese companies continues, which can be confirmed by the last decision of Donald Trump, the president of the United States.
According to the decision of Donald Trump, every employee of the US government was banned from using any devices manufactured by Chinese companies. If anyone is in possession of such a device, he or she must immediately purchase a replacement for such a device. This ban may stem from the US government's fear of spying by the Chinese government, and in this way the United States wants to increase income of US companies instead of strengthening its competitors' budgets.
