Under U.S. law, Washington is required to provide Taiwan with defensive capabilities to help the self-governing island maintain its ability to defend itself. The policy stems primarily from the Taiwan Relations Act, legislation passed after the United States switched diplomatic recognition from Taipei to Beijing in 1979.
The United States does not officially recognize Taiwan as an independent country, but it maintains close unofficial ties and continues to supply military equipment designed to strengthen Taiwan’s defenses.
Recent arms packages have included air-defense systems, missiles, radar technology, military aircraft support, naval equipment, and advanced surveillance capabilities. American officials argue these sales are intended to deter conflict and help preserve stability in the Taiwan Strait.
China strongly opposes the transfers.
Beijing considers Taiwan part of its territory and views foreign weapons sales to the island as interference in China's internal affairs. Chinese officials frequently accuse Washington of undermining regional stability and violating commitments made when diplomatic relations were established between the two countries.
The issue has become increasingly important as military activity around Taiwan has intensified in recent years. Chinese military exercises near the island have grown larger and more frequent, while Taiwan has accelerated efforts to modernize its armed forces.
Security experts say the dispute reflects a broader geopolitical competition between the United States and China across the Indo-Pacific region.
Supporters of the arms sales argue that a well-equipped Taiwan reduces the risk of conflict by making military action more costly and difficult.
Critics, however, warn that continued weapons transfers could further strain U.S.-China relations and contribute to a cycle of escalating military tensions.
For both Washington and Beijing, Taiwan remains one of the most sensitive and potentially dangerous flashpoints in international politics.
