WASHINGTON, March 25 (Reuters) - Six subsidiaries of

Inspur Group, China's leading cloud computing and big data

service provider, were among dozens of Chinese entities added to

the U.S. Department of Commerce's export restriction list on

Tuesday, according to government postings.

The Inspur units were listed for contributing to the

development of supercomputers for the Chinese military, the

Commerce department said in a posting. Five of the subsidiaries

are based in China and one in Taiwan. Inspur Group itself was

placed on the list in 2023.

The U.S. adds companies to the Commerce department's

Entity List, as it is called, for acting contrary to national

security or foreign policy interests. Companies cannot sell

goods to those listed without applying for and obtaining

licenses, which are likely to be denied.

The Inspur Group did not immediately respond to a

request for comment.

When Inspur Group was placed on the list in 2023,

executives from AMD and Nvidia ( NVDA ) were questioned

about their dealings with the company. At the time, chip

industry insiders and their advisers said firms were trying to

assess whether they had to halt supplying Inspur's subsidiaries.

Reuters could not immediately determine whether the U.S.

companies continued to do business with the subsidiaries.

Nvidia ( NVDA ) declined to comment, and AMD did not immediately

respond to a request for comment.

The Inspur units are among about 80 companies and

institutes added to the Entity List on Tuesday. Over 50 are

based in China. The others are in Taiwan, Iran, Pakistan, South

Africa and the United Arab Emirates.

Chinese firms Nettrix Information Industry Co, Suma

Technology Co, and Suma-USI Electronics, are among the other

companies added to the list. The U.S. said they were added for

helping develop Chinese exascale supercomputers, which can

process vast amounts of data at very high speeds and conduct

large-scale simulations.

The companies also have provided manufacturing capabilities

to Sugon, also known as Dawning Information Industry Co

, a computer server manufacturer added to the Entity

List in 2019 for building supercomputers used by the military,

the Commerce department said.

The companies could not immediately be reached for

comment.

Other companies were added to the list for acquiring

U.S.-origin items to advance China's quantum technology

capabilities, and for selling products to companies who supply

other listed parties, including Huawei, the tech conglomerate

viewed as at the center of China's AI ambitions.
