The US government is said to have blacklisted SMIC, the largest chip maker in China.
The British business newspaper
on Saturday based on a non-public government document.
In it, the US Department of Commerce would write that there is an "unacceptable risk" that goods supplied to SMIC will be used for Chinese military purposes.
The American sanction makes it more difficult for SMIC - which stands for Semiconductor Manufacturing International Corporation - to do business with American companies.
The company still uses American products to make its chips.
As a result of the measure, American companies would from now on need a license to be able to supply SMIC.
The chipmaker says in a response to the
that he has not been informed by the US and emphasizes that he has no ties with the Chinese army.
At the beginning of this month, it was already reported that the US government was planning to blacklist SMIC.
