China has passed a law to strengthen its export controls on products related to national security. This is viewed as a reaction to the United States' moves against Chinese companies.
China's state-run Xinhua news agency reports that the Standing Committee of the National People's Congress adopted the legislation on Saturday.
The law will take effect on December 1, banning or restricting exports of products, technologies, and services pertaining to national security.
The law will apply to foreign-capitalized firms and other entities deemed to possibly threaten China's security. But it currently remains unclear what specific items the law will cover.
The law will also restrict exports of products that are manufactured outside China using materials shipped from the country.
The law could fuel US-China tensions that have heightened partly due to Washington's tightened regulations on supplies to Chinese telecom giant Huawei Technologies.
