Chinese President Xi Jinping invoked the 'Thucydides Trap' during his summit with US President Donald Trump, highlighting Taiwan as the most critical flashpoint in US-China relations, with historical precedents of near-conflict scenarios.

Key points

Thucydides Trap refers to the theory where a rising power (China) threatens to displace an established one (US), making war likely. Xi's invocation signals Beijing's view of Taiwan as a non-negotiable sovereignty issue.

Taiwan's Strategic Value extends beyond territorial claims—it produces 90% of the world's advanced semiconductor chips through TSMC, making it critical for global tech supply chains and military applications.

Historical Context: The 1954-55 Taiwan Strait Crisis saw PRC shelling ROC-held islands, leading to the US-Taiwan Mutual Defense Treaty and Formosa Resolution authorizing US military intervention.

1958 Crisis nearly escalated into nuclear conflict before negotiations eased tensions, demonstrating how Taiwan remains a persistent flashpoint in US-China relations.

[GS3-Economy] Taiwan's semiconductor dominance means any conflict would disrupt global supply chains, affecting everything from smartphones to AI systems, with cascading effects on financial markets.

One China Policy sees the US diplomatically recognizing Beijing while maintaining unofficial ties and arms sales to Taiwan under the Taiwan Relations Act—a deliberate ambiguity that Beijing challenges.

Way Forward: The US should maintain strategic ambiguity while strengthening Taiwan's asymmetric defense capabilities, pursue multilateral dialogues under UN frameworks to de-escalate tensions, and diversify semiconductor supply chains to reduce global vulnerability.

Key terms

Thucydides Trap

A term popularized by Graham Allison describing the inevitable conflict when a rising power challenges an established one, derived from Thucydides' account of the Peloponnesian War. For UPSC, this concept is crucial for understanding US-China rivalry dynamics in GS2 International Relations.

Taiwan Relations Act

A 1979 US law maintaining unofficial relations with Taiwan while recognizing Beijing, mandating arms sales for Taiwan's self-defense. Its constitutional significance lies in balancing strategic ambiguity with regional security commitments under Article II treaty powers.

One China Policy

The diplomatic framework where countries recognize the PRC as China's sole legitimate government, acknowledging Beijing's claim over Taiwan without endorsing it. This policy is central to GS2 questions on India's Taiwan policy balancing act.

Semiconductor Supply Chains

The global network producing advanced chips concentrated in Taiwan (TSMC), South Korea (Samsung), and the US (Intel). For GS3, disruptions here would impact India's electronics manufacturing, AI development, and strategic autonomy in critical technologies.
