The Trump Administration on Monday announced that the temporary license allowing U.S. companies to do business with Chinese telecommunications group Huawei had been extended by 90 days.

After adding Huawei to an economic blacklist in May citing national security concerns, the U.S. Commerce Department has allowed it to purchase some American-made goods in a series of 90-day license extensions that it says aim to minimize disruption for its customers, many of which operate networks in rural America.

“The Temporary General License extension will allow carriers to continue to service customers in some of the most remote areas of the United States who would otherwise be left in the dark,” Secretary of Commerce Wilbur Ross said in a statement.

“The Department will continue to rigorously monitor sensitive technology exports to ensure that our innovations are not harnessed by those who would threaten our national security,” he added.

The development comes amid discussions between the United States and China aimed at coming to an initial agreement to resolve a trade war that has lasted for over a year.
