Huawei Technologies has dismissed a new 90-day extension by the Trump administration allowing U.S. firms to continue doing business with the Chinese company as making little difference, repeating that it was being unfairly treated.

After adding Huawei to an economic blacklist in May, the U.S. Commerce Department has the Chinese company t to purchase some American-made goods. Its 90-day license extensions aim to minimize disruption for its customers, many of which operate networks in rural America.

Huawei said the decision to add it to the list had caused more harm to the U.S. than to Huawei.

“This has done significant economic harm to the American companies with which Huawei does business,” it added.

Huawei said on Monday that the latest extension would not “have a substantial impact on Huawei’s business either way”.

“This decision does not change the fact that Huawei continues to be treated unfairly either,” the Chinese firm said.

Th United States and China try to resolve a trade war with Huawei to be one of its most visible targets.

The Commerce Department is also considering whether to grant individual licenses for U.S. firms to sell components to Huawei after receiving more than 200 requests.
