Caught in the tug-of-war between the US and China, TSMC's success is a walk on the razor's edge. So it is for Taiwan, the island TSMC sits on. The Pentagon is pressuring the US government to invest more in advanced chipmaking locally so that its missiles and fighter jets are not dependent on Taiwan, a self-ruling island that China believes it owns and threatens to invade. This presents a quandary to Taiwan as American firms account for 65 percent of all TSMC sales while China, by virtue of its role as the world's factory, imported around $415 billion worth of chips in 2022 alone.
