The United States has been lobbying for months to prevent its western allies from using Huawei equipment in their 5G deployment, and on Wednesday, Washington made it more difficult for the Chinese telecom titan to churn out those next-gen products.

The U.S. Department of Commerce announced that it will add Huawei and its 70 affiliates to the so-called ‘Entity List,’ a move that will prevent the telecom giant from buying parts and components from U.S. companies without approval from Washington. That confirms reports of the potential ban a day before.
