United States (US) President Donald Trump gives another pressure on China to reach a trade deal. Trump signed an order to restrict access for Huawei Technologies Co., into the US market and suppliers.

Shortly afterward, the US Commerce Department said it had put Huawei and 70 of its affiliates on a blacklist that could prohibit it from doing business with American companies. In the executive order, which didn’t name any countries or companies, Trump declared a national emergency relating to threats against information and communications technology and services. That could effectively halt business for some of Huawei’s product lines that rely on American suppliers.

The department’ move to put Huawei on its “Entity List”, means US companies will need a special license to sell products to the Chinese company. A similar move against ZTE last year nearly forced the company to shut down before Trump intervened and a deal was reached.
