‘Trump returned exactly as he went’: China summit falls into Xi’s ‘Thucydides Trap’ with failed talk

Key Concepts

• Thucydides Trap: A theory suggesting that when a rising power threatens to displace an established superpower, the resulting structural stress often leads to conflict.
• One-China Principle: The diplomatic position that there is only one China, Taiwan is an inalienable part of its territory, and the People's Republic of China (PRC) is the sole legal government.
• Strategic Stability: A framework for managing the China-US relationship to prevent escalation and ensure sustainable, predictable interactions.
• UNGA Resolution 2758 / WHA Resolution 25.1: Legal instruments cited by China to reinforce its claim over Taiwan and its status within international organizations.
• Remilitarization: The process of a nation increasing its military capabilities, specifically referenced here regarding Japan’s current geopolitical trajectory.

1. Overview of the May 2026 Beijing Summit

On May 13, 2026, Donald Trump visited Beijing for a high-level summit with President Xi Jinping. Despite the high stakes, the summit concluded without the signing of major agreements regarding Iran, Taiwan, rare earth exports, semiconductors, or sanctions. Critics characterized the visit as "empty-handed diplomacy," noting a perceived disparity in body language: Trump appeared restrained, while Xi projected confidence. Both leaders agreed to continue negotiations later in the year in Washington.

2. Geopolitical Frameworks and Regional Security

• The Thucydides Trap: President Xi Jinping explicitly invoked this concept to frame the current state of US-China relations, highlighting the inherent risks of a rising power challenging an existing hegemon.
• Japan’s Role: China expressed significant concern regarding Japanese "right-wing forces," accusing them of challenging the post-WWII international order. China urged Japan to cease "remilitarization" and rectify its stance on Taiwan to regain the trust of its neighbors.
• Korean Peninsula: China reiterated its commitment to a political settlement, emphasizing that parties must address the "root cause and crux" of the issue rather than relying on escalation.

3. The Taiwan Question

China’s stance on Taiwan remained the most rigid aspect of the summit. Key arguments included:

• Status Quo: China maintains that the "real status quo" is that the mainland and Taiwan belong to one China.
• Opposition to Separatism: China condemned the DPP (Democratic Progressive Party) and Lai Ching-te, labeling them as "destroyers of the status quo" and "troublemakers."
• External Interference: China firmly opposes US arms sales to Taiwan and any official exchanges between Taiwan and countries with diplomatic ties to the PRC.
• Strategic Ambiguity: During a press interaction, Trump was questioned on whether the US would defend Taiwan militarily. He declined to provide a definitive answer, stating, "I don't talk about that," and noted that he had maintained this position during his private discussions with President Xi.

4. Economic and Trade Relations

While no major breakthroughs were announced, the Chinese side reported that economic and trade teams held talks characterized by "equality, respect, and mutual benefit." The stated goal is to move toward a "constructive China-US relationship of strategic stability." Additionally, China criticized the "overstretching" of national security concepts to block foreign investment, specifically referencing concerns regarding Australia’s business environment for Chinese investors.

5. Synthesis and Conclusion

The 2026 Beijing summit serves as a case study in "managed competition." While the lack of concrete deliverables suggests a stalemate on critical issues like semiconductors and regional security, the commitment to ongoing high-level dialogue indicates a mutual desire to prevent the "Thucydides Trap" from manifesting into open conflict. The summit underscored a fundamental divergence: the US maintains strategic ambiguity regarding its defense commitments, while China continues to assert the One-China principle as a non-negotiable prerequisite for regional stability. The primary takeaway is that both powers are currently prioritizing the establishment of communication channels over the resolution of deep-seated ideological and territorial disputes.
