In a notable exchange in May, Chinese President Xi Jinping posed a question to U.S. President Donald Trump about whether the United States and China could escape a destructive pattern of rivalry. That question — invoking the spectre of escalating strategic competition — has since been followed by a tone and conduct from Beijing that observers interpret as a belief the two countries can manage their differences without sliding into confrontation.
The term "Thucydides Trap" refers to a historical pattern attributed to the ancient Greek historian Thucydides, who wrote that the rise of Athens and the fear it inspired in Sparta made war inevitable. In contemporary international relations, the phrase is used to describe the risk that a rising power will clash with an established one. Leaders, analysts and policymakers from both sides have warned about the applicability of that concept to U.S.-China ties and have debated ways to reduce the risk of conflict.
Chinese leaders' public comments and diplomatic interactions since May have been read by many as reflecting cautious optimism that rivalry can be restrained. Rather than accepting inevitability, Beijing appears to be signalling willingness to explore mechanisms for managing competition and seeking avenues for cooperation. That posture leaves open the possibility of negotiated arrangements on trade, security, technology and other contentious areas, though concrete outcomes depend on reciprocal steps by Washington.
Avoiding the Thucydides Trap would carry significant implications for global stability. If both capitals are committed to conflict avoidance, it could create space for collaboration on transnational challenges such as climate change, pandemic response and economic volatility, while still allowing for competition in other domains. But the prescription is difficult: it requires sustained diplomatic engagement, clear communication channels, and mutual restraint.
Ultimately, whether Xi's apparent confidence proves well-founded will hinge on policy choices made in Beijing and Washington alike. The leaders of the two countries will need to translate rhetorical willingness into durable institutions and practices to manage rivalry — a task that will test political will on both sides and shape international relations for years to come.
