Lessons from the 2025 G7 Cycle: Quantum, AI and Science Diplomacy

Policy Brief No. 237

May 12, 2026

The 2025 G7 convened at a time of international instability. Nevertheless, its meetings achieved meaningful progress on emerging technologies. The 2025 G7 cycle’s outputs focused on scope, rather than concluding with a wide-ranging statement about geopolitical order, a fundamentally different perspective for middle powers.

Michael P. A. Murphy argues that middle powers can use strategies of science diplomacy to navigate the current instability of international relations. Technical aspects of science policy have the potential to facilitate continued cooperation amid growing international tensions, as has been demonstrated by the key emerging technology outputs of the 2025 G7 cycle, and by emphasizing technical cooperation rather than debates on international order, middle powers can support the resilience of international institutions.
