Chinese President Xi Jinping told President Trump during their meeting in Beijing that the major question facing China and the United States is whether both nations can avoid the "Thucydides Trap," a historical concept describing how tensions between rising and established powers often lead to conflict. Xi asked if both countries could "overcome the Thucydides Trap and create a new paradigm of major country relations," according to CCTV, citing CNBC. The Chinese president also warned that Taiwan tensions remain a significant point of contention, stating that "'Taiwan independence' and cross-Strait peace are as irreconcilable as fire and water."
The concept of the Thucydides Trap was popularized in the early 2010s by Harvard University political scientist Graham Allison. The term draws from ancient Athenian historian Thucydides, who wrote in his late 5th century B.C. text "History of the Peloponnesian War" about the conflict between Athens and Sparta: "It was the rise of Athens and the fear that this instilled in Sparta that made war inevitable." Allison applied this framework to U.S.-China relations in his book "Destined for War: Can America and China Escape Thucydides's Trap?"
What the Right Is Saying
Conservative Republicans and national security hawks view Xi invoking the Thucydides Trap as an acknowledgment of Chinese ambitions to displace American leadership in the Indo-Pacific. Senator Tom Cotton (R-AR) has been a vocal advocate for strengthening U.S. military presence in the region to deter Chinese aggression. "Every administration since Nixon's opening to China has hoped engagement would liberalize Beijing—it hasn't," Cotton said during a 2024 foreign policy speech.
Supporters of a tougher China posture argue that Xi explicitly linking Taiwan tensions to irreconcilable differences underscores why the U.S. must maintain its commitment to Taiwanese self-defense capabilities. Conservative commentators, including those at the American Enterprise Institute, contend that peaceful rises are possible only when rising powers accept international norms rather than seeking to rewrite them. Republican foreign policy voices have largely supported maintaining or expanding economic pressure on China while strengthening alliances with Japan, South Korea, and Australia.
What the Left Is Saying
Progressive Democrats and foreign policy critics have used the Thucydides Trap framework to argue for diplomatic engagement over confrontation. Senator Chris Murphy (D-CT), a member of the Senate Foreign Relations Committee, has long advocated for finding cooperative pathways with China rather than treating it purely as an adversary. "The question isn't whether China will challenge American influence—it already does—but whether we can manage that competition without it becoming catastrophic," Murphy has argued in committee hearings.
Human rights advocates aligned with progressive causes note that Xi raised the Taiwan issue during these talks, pointing to China's military modernization and pressure campaigns against Taipei. Organizations such as Human Rights Watch have called for the U.S. to balance strategic competition with support for democratic institutions in the region. Some progressive analysts argue that framing every interaction through a great-power rivalry lens risks oversimplifying complex economic interdependence between the two nations.
What the Numbers Show
Graham Allison's research examined 16 historical cases where a rising power challenged an established one. According to his analysis published through Harvard's Belfer Center for Science and International Affairs: 12 of those rivalries ultimately ended in military conflict, while only 4 avoided large-scale violence. The cases span from ancient Greece through the Cold War era.
Specific examples cited by Allison include the U.S.-Japan rivalry in the early 20th century, which culminated in World War II after Japan's attack on Pearl Harbor—Allison characterizes Japan as the rising power and the United States as the ruling power at that time. The Soviet Union-United States Cold War represents a case where the threat of war did not escalate to direct large-scale conflict, despite proxy wars. Allison identifies post-Cold War relations between Germany (as a rising European power) and the established U.S.-United Kingdom-France alliance as the most recent example of a rising power achieving status through economic means rather than military expansion.
The Bottom Line
The Trump-Xi meeting's reference to the Thucydides Trap reflects growing acknowledgment on both sides that managing U.S.-China relations carries significant stakes for global stability. Xi framing Taiwan as fundamentally incompatible with cross-Strait peace signals Beijing's continued emphasis on unification, while the Thucydides concept itself serves as a diplomatic warning about escalation risks.
What happens next will likely depend on several factors: whether military channels remain open to prevent miscalculation, how trade negotiations proceed amid tariff disputes, and whether both sides find areas for limited cooperation in climate or pandemic preparedness. Analysts from both political perspectives agree that the coming months of bilateral engagement will test whether the world's two largest economies can forge a new paradigm—or whether historical patterns prove difficult to escape.
