U.S. President Donald Trump’s two-day visit to China on May 14–15—the first in nearly a decade—turned out to be more of a spectacle than a diplomatic breakthrough and failed to yield any tangible results.
It was not empty diplomatic rhetoric. It was a calm, historically grounded challenge delivered by the leader of the rising power directly to the leader of the established one in the established one’s own language of historical reference.
What the Thucydides Trap Actually Means
The concept originates with the ancient Greek historian Thucydides, who explained the Peloponnesian War not through ideology or morality, but through structural inevitability: it was the growth of Athenian power and the fear this caused in Sparta that made war unavoidable.
Harvard political scientist Graham Allison popularized the term in his 2017 book Destined for War, examining sixteen historical cases of rising powers challenging established hegemons across five centuries. In twelve of those cases, the result was war. Allison’s framework is the very thesis that Xi Jinping effectively paraphrased and delivered straight to Trump’s face.
By invoking the trap openly, Xi was saying something precise and uncomfortable: China is rising. The United States is the established hegemon. The structural tension between them is not manufactured by ideology or misunderstanding — it is structural. The question is whether America possesses the strategic maturity to accept a multipolar world, or whether fear and pride will drag both powers — and everyone between them — into unnecessary confrontation.
The Meeting: Spectacle and Substance
Trump arrived in Beijing accompanied by a roster of American corporate titans — Apple’s Tim Cook, Tesla’s Elon Musk, Nvidia’s Jensen Huang — signalling that business access to China’s vast market was among his top priorities. The ceremony at the Great Hall was grand. The flags were prominent. Trump performed for the cameras with visible satisfaction.
Xi played a different game. While Trump smiled and shook hands, Xi remained composed and presidential. The two leaders agreed to develop a “constructive China-US relationship of strategic stability” — a framework Beijing intends to treat as guiding for the next three years and beyond. Xi offered the spectacle Trump’s ego required while retaining firm control over the substance of what was actually agreed.
America Arrives as a Petitioner
Beneath the flags and banquets, the structural reality of this summit was uncomfortable for Washington. China controls approximately 60% of global rare earth mined supply and 91% of global refining and processing capacity — materials without which modern military systems, fighter jets, missiles, drones and advanced electronics cannot function.
China’s export controls imposed in April 2025 caused sharp declines in exports of rare earths and permanent magnets, leading to production disruptions in the US and Europe. Even after partial easing, Chinese customs data still shows critical categories running significantly below pre-2025 levels. The United States, the world’s dominant military power, arrived in Beijing carrying a structural dependency it cannot quickly resolve. Washington did not come to dictate terms. It came to negotiate relief from a chokehold it allowed to develop over decades.
Iran and the Trap Already in Motion
The shadow over the summit was the ongoing tension in the Strait of Hormuz. US military operations have disrupted oil flows through this critical chokepoint, directly affecting China — the world’s largest oil importer. The disruption raises energy prices and creates economic drag for Beijing. Yet it was Xi, not Trump, who arrived with the cleaner strategic hand.
This is what falling into the Thucydides Trap looks like in practice: not one dramatic miscalculation, but a series of assertive moves that signal an inability to accept that influence must now be shared rather than unilaterally asserted. The United States remains the last major power still behaving as if the unipolar moment is merely paused rather than structurally over.
Xi’s Offer and Its Limits
Xi’s message was, at its core, an offer: “We must make it work and never mess it up.” China is signalling that it remains willing to work toward a stable multipolar framework — one in which rising and established powers coexist without catastrophic collision.
The offer is genuine but not unconditional. On Taiwan, Xi was unequivocal, calling it “the most important issue in US-China relations” and warning that mishandling it would create “a very dangerous situation.” This is the red line Beijing will not cross. Xi can accommodate Trump on trade, fentanyl or rare earths. He cannot accommodate him on the fundamental question of Chinese sovereignty.
The European Angle: Watching from the Margins
For Europe, and especially for Poland, today’s summit is a sobering reminder of the structural shift now underway. Deeply dependent on American security guarantees and still committed to the old transatlantic order, the continent risks becoming collateral damage if Washington and Beijing fall into the Thucydides Trap, or a marginalized spectator if they succeed in constructing a new framework of strategic stability.
Poland occupies a unique geographic position at the crossroads of the European continent. In an emerging multipolar order, this location offers the genuine possibility of evolving from a frontline state into a pragmatic Eurasian bridge — a natural connector between the two eastern great powers, Western Europe, and the transatlantic realm.
Xi’s message in Beijing carries a broader lesson for the entire Old Continent: the three major powers are redefining the rules of the game. Europe, with Poland at its geographic centre, is ideally placed to act as a stabilizing link rather than a passive victim. Failure to seize this window of opportunity could mean that the Thucydides Trap — originally a contest between two powers — will engulf the continent through ricochet effects.
A Choice Still Available
Xi Jinping’s invocation of the Thucydides Trap was not merely philosophical. It was a diagnosis and an offer at the same time. China is signalling that catastrophic confrontation is not inevitable — that the structural tension between rising and established powers can be managed if both sides accept the constraints of a genuinely multipolar order.
Whether the United States possesses the wisdom and institutional capacity to accept those constraints — to govern rather than dominate, to negotiate rather than dictate — is the central question of this decade.
Xi has made the question impossible to avoid.
