Chinese President Xi Jinping raised the ancient Greek historian Thucydides during his meeting with US President Donald Trump in Beijing, injecting a historical perspective into discussions about modern superpower rivalry. The reference to the Thucydides Trap, a concept that suggests war is likely when a rising power challenges an established one, highlighted Xi's concerns about potential conflict between China and the United States.
What is the Thucydides Trap?
The Thucydides Trap is a term derived from the ancient Greek historian Thucydides, who chronicled the Peloponnesian War between Athens and Sparta in the 5th century BC. Thucydides wrote, "It was the rise of Athens and the fear that this instilled in Sparta that made war inevitable." In modern foreign policy, the trap refers to the idea that when a rising power threatens to displace an established hegemon, the resulting tension often leads to armed conflict. This concept has been widely discussed by analysts and policymakers, including former Trump strategist Steve Bannon.
Xi Jinping's Use of the Term
During his opening remarks on Thursday, Xi asked whether China and the United States could "transcend the so-called 'Thucydides Trap' and forge a new paradigm for major-power relations." This was a pointed reference to the potential for conflict as China's economic and military power grows, challenging US dominance. Observers noted that Xi has used the term for years, but deploying it during Trump's visit may have been a deliberate signal regarding Taiwan.
Taiwan as a Flashpoint
Xi later warned Trump that any missteps on Taiwan could push their two countries into "conflict." He stated, "The Taiwan question is the most important issue in China-US relations. If mishandled, the two nations could collide or even come into conflict, pushing the entire China-US relationship into a highly perilous situation." Taiwan is a self-governing island that China claims as its own, and it remains a major source of tension between Beijing and Washington.
A Conciliatory Note
At a state banquet later that evening, Xi struck a more conciliatory tone, insisting that the two nations could manage the seemingly inevitable friction. He said, "Achieving the great rejuvenation of the Chinese nation and making America great again can totally go hand in hand ... and advance the wellbeing of the whole world." This statement suggested a willingness to cooperate despite underlying tensions.
Trump's Response
President Trump responded on social media, noting that Xi had "very elegantly referred to the United States as perhaps being a declining nation." However, Trump quickly added that this characterization did not apply to the US under his leadership. He posted, "Two years ago, we were, in fact, a Nation in decline. Now, the United States is the hottest Nation anywhere in the world, and hopefully our relationship with China will be stronger and better than ever before!"
The exchange underscores the delicate balance between competition and cooperation in US-China relations, with historical analogies providing a framework for understanding contemporary challenges.
