Notice the flip flop here.
In 2015, Xi said that "there's no such thing as the so-called Thucydides Trap in the World" and now?
Xi just sat across from Donald Trump in the Great Hall of the People and asks whether the two powers can “overcome the Thucydides Trap” and “forge a new paradigm” for great-power relations.
Funny! Because a decade ago, he used the phrase "so-called" to describe it and outright denied that it was an applicable concept.
So why the change of tone you ask?
This is what you'd call a tell, an involuntary admission that Beijing’s position has deteriorated sharply since 2015.
Back then, China was at the height of the post-financial crisis boom. Beijing was surging with double digit growth (on paper), the Belt and Road Initiative was rolling out to great fanfare, island building in the South China Sea was barely met with any Western response (thanks Obama), and the American president was still preaching “strategic patience.”
Today, in 2026, the material reality has flipped. China’s much-hyped “century of rejuvenation” has slammed into structural headwinds that no amount of state media spin can hide - a demographic death spiral, a property sector collapse that wiped out trillions in household wealth, local government debt bombs lurking on the books, and a tech ecosystem increasingly isolated by US export controls and friend-shoring.
The GDP overtake narrative that once enthralled the elites at Davos has quietly died; projections now show America pulling further ahead in nominal terms. Xi’s “China Dream” is at best delayed and at worst, never materializing.
Trump 2.0 brought tariffs back on the table, hardened alliances with Japan and the Philippines, accelerated arms sales to Taiwan, and an American public finally awake to the CCP’s game. Knowing that China requires continued access to Western markets, capital, and technology to avoid stagnation at home, Xi now does a U-Turn and reaches for the historical analogy he once dismissed.
Basically when you’re strong, you deny any threat exists hoping to lull the bigger power into complacency.
When your power and strength wanes, warn that resistance will produce the very conflict you claim to fear.
Xi is essentially saying to America, "don't contain us, don’t push back too hard, or you’ll be the paranoid Sparta that started the war against Athens.”
It's actually a veiled threat to keep the one-way transfer of power and wealth open, OR ELSE. This 180 deg shift proves that the balance is tilting back toward American strength.
The correct US response is to reject the premise entirely, and continue to maintain unrelenting pressure on every front and force Xi to choose between genuine reform at home or managed decline on Beijing’s terms. Xi’s sudden invocation of the Thucydides Trap - something he used to dismiss - simply confirms that the pressure worked.
Americans should take this as a sign that their country is not in decline, despite the insane amount of propaganda now also being touted by American influencers and podcasters.
Xi Jinping asked Trump if the United States and China can avoid the 'Thucydides Trap', a theory that suggests high likelihood of war between rising and established powers, during their summit.
