The US has been targeting Chinese companies and cracking down on them in the name of National Security especially since last year. Beijing says it's against Washington's practice of pressuring Chinese companies for political ends, and says the country will protect them if necessary. Wu Guoxiu has this.

One of the US' obvious targets was ZTE, a manufacturer of telecoms equipment based in Shenzhen. Last year, the US Commerce Department banned American companies from selling components to ZTE for seven years. This May, the US drew China's global 5G leader Huawei into the heart of the two countries' trade dispute.

US President Donald Trump signed an administrative order against the firm, calling it threat to national security, and forbidding it from accessing US technologies without special government approval.

Huawei has repeatedly denied the accusations, and says the charges are not supported by any factual evidence.

A few days later, a leading drone producer, Dajiang, was targeted by the US Department of Homeland Security. It issued an alert reminding users to be vigilant when buying drones from China, alleging the products could steal sensitive data.

Dajiang issued a statement emphasizing that security is the company's core value. The statement also pointed out that every day, US companies, emergency personnel, and government departments rely on DJI drones to save lives, improve safety, and support their operations.

These firms, are just some of the Chinese tech companies being targeted by Washington. China's Foreign Ministry says the country will protect its companies from the attempted crackdown.

LU KANG, SPOKESPERSON CHINESE FOREIGN MINISTRY "I'd like to reaffirm this. China strongly opposes the US cracking down on Chinese companies with national force. We urge the US side to stop the wrong-doing, treat Chinese companies equally, to create conditions for firms from both countries to carry out normal trade and cooperation. China will continue to take necessary measures, to safeguard Chinese companies' legitimate rights."

WU GUOXIU BEIJING "Some experts say there is yet a silver lining for China, because the US trade war and tech blockade have exposed the dependency of Chinese enterprises on US high-tech exports, especially chips which are used in nearly all digital products. Analysts say China should develop its own chip-industry and become self-sufficient in the sector. Wu Guoxiu, CGTN, Beijing."
