China said new US export restrictions targeting companies including Huawei Technologies may threaten the global supply chain.
Beijing opposes the new US rules and will take all necessary measures to defend the rights and interests of Chinese companies, the ministry of commerce said in a statement on Sunday.
The US on Friday moved to prevent sales to Shenzhen-based Huawei by chip makers using American technology.
The commerce department said it would require licences before allowing US equipment to be used by the Chinese company or its 114 subsidiaries, including its chip design unit HiSilicon.
The new rules require any foreign chip maker that uses American gear to get a licence before they can sell to companies on a US blacklist, a roster that includes Huawei and other prominent Chinese tech giants such as SenseTime Group and Megvii Technology.
