U.S. President Donald Trump has threatened a naval blockade in the Strait of Hormuz, raising new concerns for Taiwan. The announcement has highlighted the island’s vulnerability, as it relies heavily on imported energy to sustain its population of 23 million and its semiconductor industry, which produces about 90 percent of the world’s most advanced chips. Most of Taiwan’s energy shipments arrive by sea from the Middle East, entering through a few western ports.

China has long prepared strategies to pressure Taiwan, including military exercises simulating port and sea route blockades. The People’s Liberation Army now possesses the world’s largest navy, capable of extended operations. Beijing continues to frame the Taiwan issue as an internal matter while criticizing U.S. actions in Iran and Venezuela, which analysts say could serve as justification for similar Chinese measures.

Facing potential energy shortages, Taiwan may impose restrictions on air conditioning, elevators, street lighting, and business hours. The government is reconsidering nuclear power and reviewing plans to restart inactive reactors, though such steps could take years due to safety and regulatory requirements.
