The Trump administration announced on Monday it will further tighten restrictions on Huawei Technologies Co., aimed at cracking down on its access to commercially available chips.

The U.S. Commerce Department actions will expand restrictions announced in May aimed at preventing the Chinese telecommunications giant from obtaining semiconductors without a special license — including chips made by foreign firms that have been developed or produced with U.S. software or technology.

The administration will also add 38 Huawei affiliates in 21 countries to the U.S. government's economic blacklist, the sources said, raising the total to 152 affiliates since Huawei was first added in May 2019.
