The confrontation came just days after the Trump administration imposed AI export controls on Anthropic, blocking the company from exporting its newest Mythos 5 and Fable 5 models on national security grounds

1

. The order forced Anthropic to disable access to these models for all users worldwide, including the company's own employees

. The sudden shutdown created alarm among international companies and governments that had built their operations on US AI infrastructure, now facing the reality that access could be revoked overnight without warning.

AI Executives Propose US-Led Coalition Amid Export Restrictions

Despite the tensions, Anthropic CEO Dario Amodei and Google DeepMind's Demis Hassabis called for a US-led AI coalition to shape international rules and standards around artificial intelligence during the G7 summit meeting

. Amodei told the group that areas of international cooperation should include structured access to frontier AI models and trade of chips and critical components that excludes China

2

. He also emphasized that countries should cooperate to address the risk of AI in cyber operations, bioterrorism, and intelligence

Canadian Prime Minister Mark Carney agreed that the US could lead such a coalition, according to sources familiar with the discussions

2

. Sam Altman, OpenAI CEO, called for "an international forum for discussion that establishes globally accepted standards for testing, provides expert and impartial analysis of capabilities and risks, and serves as a venue for cooperation among nations"

2

. The meeting included about a dozen tech executives alongside G7 heads of state, with Treasury Secretary Scott Bessent, Commerce Secretary Howard Lutnick, and Secretary of State Marco Rubio representing the US

Digital Sovereignty Concerns Drive Push for Trusted Partners Scheme

The episode has intensified discussions around digital sovereignty, with leaders exploring a "trusted partners" scheme that would grant access for non-US nations to advanced AI models from firms like Anthropic and OpenAI

1

. The goal is to maintain an open trade network that bypasses US restrictions, with both countries and companies qualifying as trusted partners as long as they use the models to develop stronger defenses against rivals like China

.

Aidan Gomez, co-founder and CEO of Canadian enterprise AI firm Cohere, stated: "The recent restriction on access to Anthropic's models confirms what we at Cohere have known all along: that companies and democratic nations remaining dependent on a small handful of big tech companies is dangerous to resilience. Digital sovereignty is not just about market competition or any one company or nation. It's about who controls the foundational technology that will shape our economic security and national sovereignty for decades to come"

National Security Justifications Meet International AI Governance Challenges

The Trump administration blocked Anthropic's models after Amazon flagged to the White House that certain AI safety guardrails could be bypassed

1

. However, cybersecurity experts have argued that the capabilities cited by the government are also present in models that remain freely available, including from OpenAI

1

. The models have shown effectiveness at uncovering bugs in software, creating global alarm that hackers might abuse the technology

During the working lunch, Dario Amodei called on world leaders to share the benefits of AI among democratic nations and suggested it would be possible to coordinate the trade of powerful AI technologies among them while excluding China

4

. Demis Hassabis called for an international standard-setting body that could enact rules on AI development to ensure it was done safely while still encouraging innovation, noting that the challenges presented by AI are economic, philosophical and technical, and shouldn't be left to AI companies to solve on their own

Geopolitical Tensions Shape Future of International AI Cooperation

The gathering produced no binding commitments or regulatory announcements, with multiple accounts describing it as a conversation rather than a negotiation

3

. The G7's track record on international AI governance, from the Hiroshima AI Process in 2023 to Canada's 2025 presidency pledges, has so far yielded principles and codes of conduct but no enforceable regulation

3

.

Meanwhile, China is positioning itself as an alternative. Senior Chinese officials stressed Beijing's plans to share artificial intelligence globally and safely, with top diplomat Wang Yi announcing that "China is accelerating the establishment of a global AI cooperation organization, and welcomes all parties to join"

5

. This development highlights how geopolitical tensions are driving different approaches to AI governance, with the US and China promoting competing visions for the technology's future.

The tension underscores how AI labs are simultaneously positioning themselves as indispensable partners to Washington on global technology competition while pushing back against the controls Washington imposes on their own products

3

. Whether a US-led coalition materializes depends on factors well beyond what happened at a single lunch, particularly as the Trump administration has shown willingness to act unilaterally against AI companies it considers a security risk
