Chinese President Xi Jinping warned U.S. President Donald Trump that the two nations risk falling into the "Thucydides Trap" during a Beijing summit [1].
The warning highlights the precarious nature of the current global power balance. As China grows in influence, the potential for a direct military conflict with the established U.S. hegemony increases unless both nations manage their competition peacefully [2].
The summit occurred on May 15, 2026 [1], though some reports dated the meeting to May 14, 2026 [3]. During the high-stakes discussions, Xi referenced a historical pattern from the fifth century BC [2] where a rising power challenges a ruling one, often resulting in war.
“History shows that when a rising power threatens a ruling one, war is often the result,” Xi said [2].
Xi urged the U.S. president to work toward avoiding this outcome. “We must avoid the Thucydides Trap,” Xi said [2].
The Chinese leader also spoke about the possibility of escalation. “The prospect of a future US‑China war is real,” Xi said [3].
This reference to ancient Greek history serves as a cautionary tale for modern diplomacy. By framing the rivalry through a historical lens, Xi indicated that the friction between the two superpowers is not merely political but follows a structural pattern that has historically led to violence [2].
““We must avoid the Thucydides Trap.””
The invocation of the Thucydides Trap suggests that Beijing views the current U.S.-China friction as a systemic struggle for global dominance rather than a series of isolated policy disputes. By acknowledging the historical likelihood of war, Xi is signaling that the risk of conflict is an inherent part of China's rise, placing the onus on both administrations to create new diplomatic frameworks to prevent a catastrophic military confrontation.
