After granting a first 90-day deadline last May, Washington is giving another three months to some companies to "wean themselves off" from the Chinese smartphone brand.

Washington extended Monday's 90-day exemptions that allow Chinese telecom giant Huawei to continue doing business in the United States, US Trade Minister Wilbur Ross said Monday.

Give businesses time to wean themselves

"There are 90 more days for US telecoms companies, including some rural companies, which depend on Huawei," Fox told Fox Business , adding, "we are giving them more time to wean themselves off." Washington had already granted a first deadline before imposing sanctions.

The United States believes that Huawei poses a risk to national security and wants to ban it from the country, but Washington has granted exemptions to some US companies to continue selling low-tech products or switching suppliers.

This interim regulation, which prevents any US federal agency from acquiring telecommunication or technological equipment from these groups, is the latest episode of the Trump Administration's campaign against Huawei in the United States. US officials say the Chinese group is linked to Beijing's intelligence services.
