US and China Open AI Safety Talks as Truce Clock Ticks

Washington and Beijing discuss a joint notification system for AI incidents, even as a tariff ceasefire between the world's two largest economies nears its expiry date.

On a Sunday in New York, two of the world's most consequential economic officials sat down for what Treasury Secretary Scott Bessent described as successful talks — and left with something few observers had anticipated: a serious conversation about artificial intelligence safety. Bessent, speaking to reporters after meeting Chinese Vice Premier He Lifeng, confirmed that the two sides had discussed establishing a shared mechanism to notify each other when AI incidents arise that could threaten national security. The proposal is modest in scope but significant in symbolism, representing the first known bilateral framework of its kind between the United States and China. The timing is not accidental.

President Donald Trump and President Xi Jinping are scheduled to hold a summit in Washington later this week, and both sides appear eager to demonstrate progress on multiple fronts simultaneously. The talks in New York also covered the so-called Board of Trade, a process designed to identify potential tariff reductions on goods. That conversation carries its own urgency: the existing tariff truce between the two countries is set to expire on 10 November, raising the pressure on negotiators to show results before a damaging trade escalation resumes. The AI dimension of the talks reflects a broader tension running through Washington's technology policy.

Trump has largely dismissed calls from researchers and industry figures to slow the development of AI, arguing that the United States cannot afford to fall behind China in what he has framed as a winner-takes-all race. "Whoever wins in AI, wins," he said earlier this month. Yet agreeing to share incident notifications with Beijing implicitly acknowledges that unilateral speed carries risks that even the most competitive posture cannot ignore. The notification mechanism, if formalised, would mark a rare point of structured cooperation between two powers that have otherwise treated AI dominance as a zero-sum contest.

Huang Calls AI Extinction Fears "Irresponsible"

In a CBS News interview, Nvidia chief Jensen Huang put the probability of AI ending civilisation by 2030 at precisely zero, dismissing what he called "doomsday narratives" as unscientific and needlessly alarming. Huang directed particular scepticism at executives — notably Anthropic's Dario Amodei and OpenAI's Sam Altman — who have publicly urged a slowdown. He argued that calls for new regulation often conceal a quieter goal: relief from liability under laws that already exist. Nvidia's commercial logic reinforces his position.…

Rare Earths Race to Break China's Grip

China introduced rare earth export controls in April 2025, immediately pressuring auto and defence industries across Europe, the United States, Japan, and the United Kingdom — materials used in everything from wind turbines to military jets. Rafael Moreno, managing director of Australia-listed Viridis Mining and Minerals, calls supply diversification "paramount." His company is operating a demonstration plant in Minas Gerais, Brazil, targeting EU deliveries within two years, with further processing potentially in France. A October 2024 Trump–Xi summit produced a 12-month suspension of stricter export restrictions, but no extension has been confirmed. Kurt Tong of Washington's Asia Group warns the deal could slip to November's APEC forum — leaving markets exposed for months longer.…

Moving from opaque to more transparency between the number one and the number two AI powers in the world is very important.

IVCRITICAL THINKING
Jensen Huang argues that calls for AI regulation often hide a desire to escape existing legal liability, while rare earth export controls show that economic leverage can be used to force diplomatic concessions. Considering both articles together, to what extent do you think corporate and government actors use the language of safety or security to serve their own strategic interests rather than the public good?
