The Next Superpower Battlefield May Be a Computer Chip

As artificial intelligence transforms the global economy, the United States and China are competing for control of the advanced semiconductors that power it — placing Taiwan at the center of one of the world's most consequential geopolitical rivalries.

TAIPEI — For much of the 20th century, global power depended heavily on controlling oil. Today, another resource is becoming nearly as strategically important, although it can fit on the tip of a finger.

The advanced semiconductor has emerged as a foundation of economic and military power, powering everything from smartphones and data centers to artificial intelligence systems, advanced weapons and autonomous machines. That has placed Taiwan — and particularly Taiwan Semiconductor Manufacturing Company, or TSMC — in an extraordinary position between the United States and China.

TSMC is the world's dominant contract manufacturer of cutting-edge chips and a crucial supplier to companies developing AI technology. The artificial intelligence boom has only increased its importance. Taiwan on Friday raised its 2026 economic-growth forecast to 11.05 percent, which would be its strongest performance in nearly four decades, largely because of surging demand for AI and advanced technology.

That success carries geopolitical consequences.

China considers Taiwan part of its territory and has not renounced the use of force to achieve unification. For Washington, Taiwan's importance now extends far beyond traditional questions of democracy and regional security. A major disruption to Taiwan's semiconductor industry could reverberate through the global economy and potentially cripple industries dependent on advanced processors.

The United States has therefore been trying to reduce its reliance on Asian manufacturing while simultaneously limiting China's access to the most sophisticated technology.

Washington has imposed extensive restrictions on advanced chips and semiconductor technology destined for China. Those restrictions have become increasingly contentious as Chinese companies seek alternatives and American lawmakers debate how aggressively the rules should be enforced. Just this week, House China committee chairman John Moolenaar urged the Trump administration to prevent advanced chips from reaching sanctioned Chinese companies through intermediaries.

Meanwhile, TSMC is dramatically expanding production in the United States. The company says its planned investment in Arizona has reached $265 billion as it responds to what executives describe as strong, multiyear demand for AI chips.

China, however, is racing to develop a semiconductor industry capable of reducing its dependence on foreign technology.

The result resembles a technological arms race.

Oil powered the industrial age. Semiconductors increasingly power the digital one. Whoever controls the most advanced chips gains an advantage in artificial intelligence, robotics, surveillance, communications and sophisticated weapons systems.

That is why the tiny silicon chip has become something much larger than an electronic component.

It has become an instrument of national power — and Taiwan sits directly at the center of the struggle.
