The Trump administration added a quintet of companies to its Entity List last week, including the AMD joint venture Tianjin Haiguang Advanced Technology Investment Company (THATIC).
Coming into effect on Monday, the ban dated 18 June from the US Department of Commerce limits export licences and requires US companies to gain approval to transact with them.
The five entities added are:
- Hygon, and two aliases Chengdu Haiguang Integrated Circuit and Chengdu Haiguang Jincheng Dianlu Sheji;
- HMC, and a pair of aliases Chengdu Haiguang Microelectronics Technology and Chengdu Haiguang Wei Dianzi Jishu;

"There is reasonable cause to believe, based on specific and articulable facts, have been involved, are involved, or pose a significant risk of being or becoming involved in activities that are contrary to the national security or foreign policy interests of the United States," the Department of Commerce said.

"Sugon has publicly acknowledged a variety of military end uses and end users of its high-performance computers," the department said.
"Wuxi Jiangnan Institute of Computing Technology is owned by the 56th Research Institute of the General Staff of China's People's Liberation Army. Its mission is to support China's military modernization."
