China and Huawei lack the manufacturing capabilities needed to make some of the component parts that go into 5G systems. The U.S. Commerce Department in May restricted chip makers globally who use U.S. technology from supplying semiconductors to Huawei. This means Taiwan's Taiwan Semiconductor Manufacturing Company which uses U.S. technology in manufacturing 5G component parts cannot supply Huawei.

This gives the U.S. and Japan, South Korea to catch up with initiatives of their own to match China's state subsidies model that finances its semiconductor companies and 5G companies. 

U.S. Undersecretary of State Keith Krach says "We've utilized the strengths of semiconductor equipment companies and electronic design software companies to eliminate Huawei's access to the necessary sophisticated chips to build 5G systems and their most sophisticated smartphones." Huawei he says is a security threat to the U.S.
