The US has placed a number of Chinese companies and individuals on the sanctions list

The United States has announced that it has sanctioned nearly 400 companies and individuals who aided Russia in the Russia-Ukraine war.
According to the French International News on August 26, the United States will further restrict Russia's investment in the sale of metal and mining products through this decision. A tenth of the sanctioned companies and institutions were registered in China or Hong Kong, and one Hong Konger was charged with money laundering for Russia.
The US Treasury announced the new sanctions list on August 23, the day before Ukraine's Independence Day. Nearly 400 companies and individuals have been sanctioned inside and outside of Russia, including 60 of Russia's defense and science and technology companies. Companies outside of Russia are spread across Asia, Europe and the Middle East, and these companies are accused of providing products and services to Russia to continue the war and evade sanctions.
Among the sanctioned companies and individuals, 23 companies are registered in Hong Kong and 18 companies are registered in China. In addition, one citizen from both places was punished. They are accused of buying military-military dual-use technology and electronic components for Russian military industrial enterprises, as well as helping Russia continue its attack on Ukraine. According to foreign media statistics, more than 1,000 Chinese organizations have been placed on the US sanctions list.
The Hong Kong man, who is on the sanctions list, was accused of money laundering along with two Russians. It was revealed that they registered many dry companies in the United Arab Emirates and Hong Kong, and traded gold produced by a sanctioned Russian company into other countries' currencies or cryptocurrencies.
In addition, the US Department of Commerce's Bureau of Industry and Security has also listed 123 new companies and institutions as sanctions, including 42 Chinese companies and addresses, including three in Hong Kong designated as "high-risk transfer locations." If traders are involved in these addresses, they should obtain a business permit from the government. But getting permission can be difficult.
