The U.S. on Monday eased some restrictions imposed last week on Chinese tech giant Huawei, a rollback that will be in effect for 90 days starting on Monday. 

The U.S. Department of Commerce said in a statement the temporary exemptions will authorize specific, limited engagement in Huawei's transactions involving the export, re-export and transfer of items.  

"This license will allow operations to continue for existing Huawei mobile phone users and rural broadband networks," U.S. Secretary of Commerce Wilbur Ross said.

In response to Google's suspension of business involving the transfer of hardware, software and technical services with Huawei following the U.S. government's blacklist, the Chinese Foreign Ministry said on Monday that China will fully support Chinese enterprises in defending their legitimate rights through legal methods.

Huawei also said in a statement that the company has made substantial contributions to the development of Android around the world, and its products will not be affected in the Chinese market.

The U.S. Commerce Department on May 15 added Huawei to the "Entity List" that bans the company and its 70 affiliates from buying technology and components from American firms without U.S. government approval.

On May 19, Huawei's founder and CEO Ren Zhengfei said that the company was fully prepared for the U.S. restrictions and would be "fine" even if U.S. chipmakers would not sell chips to the company.
