With Chinese firms increasingly focusing on boosting the production of older-generation semiconductors, experts in the United States and the Western world are concerned that the development poses a significant international security threat.

The importance of such chips to the global economy has become evident in recent years as a shortage led to widespread global disruption in the manufacturing of consumer electronics and cars.
