US-China Beijing Summit Puts Taiwan Arms Deal in Doubt
A high-stakes bilateral summit in Beijing between the US and Chinese heads of government produced significant uncertainty around a pre-approved $14 billion weapons package for Taiwan, with the US president describing the sale as being held "in abeyance."
During the summit, the US president publicly characterised the arms package as "a very good negotiating chip," reframing a security commitment to a democratic partner as leverage in a broader great-power bargaining framework.
China's leadership warned that mishandling Taiwan could put the US-China relationship in "great jeopardy," reiterating that Taiwan is Beijing's foremost core interest in bilateral ties.
The summit agenda spanned trade, rare earth export controls, Iran, and Taiwan — reflecting the deeply interlocked nature of US-China disputes across economic, security, and geopolitical domains.
US lawmakers from both parties pressed the administration to maintain clear military support for Taiwan, warning that ambiguity undermines deterrence in the Taiwan Strait.
The development has renewed global attention to whether the two largest economies can manage their rivalry short of direct conflict — a question framed by scholars through the concept of the Thucydides Trap.
The Thucydides Trap
The Thucydides Trap is a concept coined by Harvard political scientist Graham Allison, derived from the ancient Greek historian Thucydides' observation that "it was the rise of Athens and the fear that this instilled in Sparta that made war inevitable," leading to the Peloponnesian War.
The Beijing summit is seen as one such attempt to manage structural rivalry — both powers choosing dialogue over confrontation — though the arms deal ambiguity shows how far trust remains from being established.
Taiwan Relations Act (TRA), 1979
The Taiwan Relations Act is a US federal law enacted in April 1979 after Washington switched diplomatic recognition from Taipei (Republic of China) to Beijing (People's Republic of China).
Taiwan's leadership has explicitly invoked the TRA to argue that arms sales are a legal commitment, not a discretionary favour — directly pushing back against the idea of using the arms package as a negotiating chip.
One China Policy vs. One China Principle
These two phrases — often used interchangeably in media — carry meaningfully different implications.
Key Details
- One China Principle (PRC position): Taiwan is an inseparable part of China; there is only one sovereign state, the PRC. This is presented as non-negotiable and absolute.
- One China Policy (US and most countries' approach): The US "acknowledges" — but does not endorse or accept — Beijing's claim. It opposes any unilateral change to the status quo by force. It does not formally recognise Taiwan as a sovereign state but maintains unofficial relations through the American Institute in Taiwan (AIT).
- The distinction matters: a "principle" is presented as immutable; a "policy" can adapt to circumstances.
- China frequently conflates the two in diplomatic messaging, claiming near-universal acceptance of its principle, while critics note most countries only accept the policy framing.
The Beijing summit is taking place entirely within the "One China Policy" framework — the US has not formally changed its position — but any signal of reduced arms commitment effectively shifts leverage toward the PRC's "One China Principle" interpretation.
Taiwan Strait and Indo-Pacific Security Architecture
The Taiwan Strait is a 180-km-wide body of water separating Taiwan from mainland China. It is both a critical commercial shipping lane and the central flashpoint in Indo-Pacific security.
Key Details
- The PLA conducted over 5,317 sorties around Taiwan in 2025, averaging 15 per day, with 3,867 crossing the Taiwan Strait median line.
- The December 2025 "Justice Mission-2025" exercise featured 130 aircraft sorties in a single day and 14 PLA Navy ships in a tighter simulated blockade than previous exercises.
- Taiwan's Air Defense Identification Zone (ADIZ) incursions have more than doubled since May 2024.
- The US, Japan, Australia, and other partners maintain freedom-of-navigation operations (FONOPs) through the strait.
Ambiguity over the $14 billion arms deal — which includes advanced air defence and missile systems — directly affects Taiwan's deterrence posture at a time when PLA military pressure is at historically high levels.
- The $14 billion arms package was approved by the US Congress in January 2026.
- Graham Allison's study found war resulted in 12 of 16 historical cases of rising-vs-ruling power rivalry.
- The TRA has been the legal basis for US arms sales to Taiwan since 1979 — nearly five decades.
- China and the US are the world's two largest economies; China is also the US's largest trading partner by goods volume.
- The Taiwan Strait handles a significant share of global container shipping traffic, making its stability a global economic interest.
- PLA Justice Mission-2025 (December 2025) had seven designated operation zones — the largest ever — some overlapping Taiwan's territorial waters.
