Chinese Commerce Ministry (MOFCOM) on Sunday blasted the US' sanctions on Chinese companies over their alleged involvement in Russia-Ukraine conflict as a typical example of long-arm jurisdiction and unilateral sanctions, vowing "necessary measures" to safeguard the legitimate rights and interests of Chinese companies.

On Friday (US time), the US imposed sanctions on more than 400 entities and individuals for allegedly supporting Russia in the Russia-Ukraine conflict, including Chinese companies, Reuters reported, citing the US State Department.

It said the Biden administration's sanctions include measures against companies in China allegedly involved in shipping machine tools and microelectronics to Russia. Meanwhile, the US also added 42 companies in China on its Entity List, forcing suppliers to obtain licenses before shipping to targeted companies, according to the report.

China firmly opposes the sanctions, a MOFCOM spokesperson said in a statement published on the ministry's website.

The practice is a typical example of long-arm jurisdiction and unilateral sanctions, which disrupts international trade norms and rules, impedes normal trade between countries, and impacts the security and stability of global industrial and supply chains, said the spokesperson. 

"We urge the US to immediately halt these misguided actions, and will take necessary measures to safeguard the legitimate rights and interests of Chinese companies," the spokesperson said.
