China has threatened to oppose US sanctions as an attempt to limit international trade in Chinese technology giant Huawei.
President of the Foreign Ministry Lu Kang said Beijing opposed countries that imposed unilateral sanctions on Chinese companies and would take action.
The Trump administration on Wednesday effectively prevented Huawei's products from being used in US networks.
The order is not called a company but is thought to target Huawei.
Huawei denies its products pose a security threat and says it is ready to engage with the United States.

Beijing accused President Trump of engaging in industrial sabotage using state security as "pretext for suppressing foreign business" .  "We urge the United States to stop this practice and instead create better conditions for business cooperation," Lu said.
He did not give any details on how China planned to oppose US sanctions.
According to a White Paper statement, Mr Trump's order aims to "protect America from foreign opponents who actively and increasingly create and exploit vulnerabilities in infrastructure and information and communications technology services."
It gives the trade secretary the power to "prohibit transactions that constitute an unacceptable risk to national security", the statement adds.
The move was immediately welcomed by the Federal Communications Commission, President Ajit Pai, who called it "an important step towards securing America's network".
The United States had already restricted the federal authorities from using Huawei products and has urged allies to disperse them, while Australia and New Zealand have both blocked the use of Huawei tools in 5G networks.
