The U.S.-China AI rivalry is being reshaped by the rapid advance of frontier models and a widening divide between U.S.-led closed systems and China’s increasingly competitive open-weight ecosystem. As AI systems become more autonomous and capable, the race for technological leadership is creating risks that traditional diplomacy and governance mechanisms may be increasingly ill-equipped to manage.

The May and September reciprocal state visits by U.S. President Donald Trump and China’s President Xi Jinping have seemingly succeeded in cementing warm personal ties between the two leaders while stabilizing an unstable U.S.-China relationship. Historians may look back on these twin summits as perhaps a turning point following a decade of tumult and steadily intensifying competition between the two powers. While the two summits have succeeded in warming the atmosphere, there remains much substantive and institutional work to do.

Moonshot AI’s Kimi is emerging as a Chinese competitor to Anthropic’s Claude, with increasingly comparable capabilities but notable differences in performance, personality and content restrictions. The comparison highlights how the two models reflect distinct technological approaches and regulatory environments as competition between the U.S. and China’s AI industries intensifies.

Britain's new prime minister, Andy Burnham, inherits a markedly different relationship with China than the "Golden Era" of a decade ago. To navigate growing U.S.-China rivalry while advancing British interests, the UK should pursue pragmatic engagement with China alongside stronger institutional coordination, economic resilience, and strategic diversification.

The current U.S. policy toward Southeast Asia is generating a range of negative effects. If the United States fails to adjust its competitive, confrontational and self-serving foreign policy, its influence in the region is likely to face further decline.

Trump’s foreign policy setbacks, particularly with Iran, have complicated his diplomatic agenda and delayed a key summit with China, though both sides remain motivated by domestic and strategic incentives to pursue limited, pragmatic agreements. However, any cooperation will likely focus on narrow, short-term gains, as deep structural rivalry and mutual distrust continue to constrain meaningful long-term rapprochement.

The recently released 2025 NSS, shows the limits of decoupling. Defending core interests while designing layered mechanisms that preserve cooperation is the only rational way for the United States and China to avoid mutual destruction and global stagnation.

Neither China nor the U.S. can change the other. They can only choose peaceful coexistence, meet each other halfway, increase mutual trust and cooperation and pursue common prosperity. Bilateral ties for the foreseeable future will follow the pattern of “fighting but not breaking up.”

In the tense relationship between the United States and China, Hong Kong emerges as a middle space — a vantage point from which to imagine a way forward. The city’s unique position offers a metaphorical middle ground for dialogue, emphasising the need for new frameworks to navigate today’s complex rivalries.

In a few short years AI technology has already become a legitimate threat to the earth’s environment. Without guardrails put in place, the competition between the U.S. and China could outstrip current infrastructure.
