Sources revealed that the United States is studying how to block the vulnerabilities existing restrictions on the Inspur Group, so as not to supply American companies such as Intel to continue to supply the subsidiary of this Chinese server manufacturer.

According to Bloomberg, the Ministry of Commerce of the United States added the "physical list" of the Inspur Group and dozens of Chinese entities this month.However, it did not indicate all the subsidiaries of the Inspur Group, and there are dozens of these subsidiaries.

People familiar with the matter revealed that officials of the White House and the Ministry of Commerce realized that the problem was trying to close the legitimate ways left.However, before the release of the revision, suppliers such as Nvidia Corp. and Cisco systems can still do business freely with the wave without being permitted by the US government.People familiar with the matter said that this may take several weeks.

The core of the problem is that the relationship between the subsidiaries of Chinese companies is complex, and the relationship with the parent company is often opaque.

The wave is an important partner of American companies such as Cisco, IBM, Intel, and directly holds the equity of about 30 companies.The company's registration information query platform Tianyan check shows that these companies involve extensive businesses, including hardware, artificial intelligence, cloud computing, investment, financial services and aviation transportation.Some subsidiaries have dozens of subsidiaries.For example, its joint venture with Cisco is buried under the third -level company.

After the United States announced the entity list last Friday, the wave information of the listed company of the Inspur Group fell 10%, and several other subsidiaries fell between 4%and 17%.Inspur information has fallen nearly 1/4 of the market value in the past week.

Earlier, Huawei, Shangtang Group and Hikvision were also included in the entity list.The list requires US companies to obtain the approval of the US government before exporting to the name entity.The U.S. Department of Commerce has told the company that the applicant should assume that these requests will be rejected.
