Huawei Technologies Co said it opposed Washington's decision to add another 46 of its affiliates to an export blacklist and called on the US government to put an end to unjust treatment to the company.

"It's clear that this decision, made at this particular time, is politically motivated and has nothing to do with national security. These actions violate the basic principles of free market competition. They are in no one's interests, including US companies," Huawei said in a statement.

The comments came after the US Department of Commerce said on Monday that it is adding 46 Huawei affiliates to the Entity List, raising the total number to more than 100 Huawei entities that are covered by the restrictions. Companies put on the Entity List are banned from buying US technology without special government approval.

"Attempts to suppress Huawei's business won't help the US achieve technological leadership. We call on the US government to put an end to this unjust treatment and remove Huawei from the Entity List," the company added.

Washington at first put Huawei on the Entity List in May, banning it from buying US technology without special government approval. Later, the US government gave Huawei a temporary license to purchase some US-made goods to reduce disruptions for its customers until Monday.

The US government also said on Monday that it will give Huawei another 90 days to buy from American suppliers. The move, an extension of the license through mid-November, is expected to allow the Chinese tech giant to serve its existing telecom customers and smartphone users.

"The extension of the temporary general license does not change the fact that Huawei has been treated unjustly. Today's decision won't have a substantial impact on Huawei's business either way. We will continue to focus on developing the best possible products and providing the best possible services to our customers around the world," Huawei added.
