The United States Commerce Department, through the Bureau of Industry and Security (BIS), has placed five Chinese companies on an export blacklist for continuing to supply Russian military defense firms after the start of the invasion of Ukraine despite sanctions.

“The sweeping export controls put in place by the United States and our allies and partners are restricting the Russian military’s ability to repair, replace, and resupply and will continue to bite harder the longer Putin persists,” Under Secretary of Commerce for Industry and Security Alan Estevez said.

The BIS has included the companies on the “Entity List,” which bars all US firms from exporting goods and services. The Chinese companies are Connec Electronic, King Pai Technology, Sinno Electronics, Winninc Electronic, and World Jetta (HK) Logistics.

“Today’s action sends a powerful message to entities and individuals across the globe that if they seek to support Russia, the US will cut them off,” Estevez added.
