The Trump administration is delaying a deadline for U.S. businesses to cut ties with Chinese telecommunications giant Huawei for the fourth time, the Department of Commerce announced Thursday.

Huawei was granted a temporary license to keep working with American companies for 45 days.

Thursday marked the fourth time the administration has extended the deadline since Huawei was added to the Commerce Department’s “entity list” in May 2019. American companies are banned from doing business with companies on the list, effectively blacklisting groups included.

Huawei was originally added to the list – which is seen a death sentence for foreign companies – because the U.S. government deemed it a national security risk.

The Commerce Department said it gave Huawei a fourth temporary license “as a measure to prevent interruption of existing network communication systems in rural U.S. regions and permit global network security measures.”

The agency suggested that American companies should not acquire new technology from Huawei during the 45 day extension.

Huawei declined to comment on the extension at the time of publication.
