Abstract The “technology war” between the U.S. and China has prompted a proliferation of export control regimes across advanced economies. In particular, the Group of 7 (G7) nations have strengthened controls on sensitive tech exports to prevent adversaries from acquiring capabilities that could threaten security. However, coordinating these controls across the G7 remains a major hurdle. Each country faces unique economic interests and legal constraints that complicate efforts to form a cohesive front. This paper examines how U.S., European, and Japanese export control policies have tightened from 2022 through late 2025, and why aligning these measures within the G7 is so challenging. The central thesis is that while national security imperatives have led to stronger unilateral controls, multilateral coordination is lagging, undermining the effectiveness of these measures. An effectively coordinated “Tech Control Alliance” could establish common lists, shared license data, and joint diplomatic stances to persuade other nations to join controls. The task is to move from reactive, ad-hoc coordination to a standing unified framework that anticipates technological advances and updates controls in real-time.
