The G20 comes together at a time when the world is changing faster than ever. Advances in artificial intelligence are reshaping economies, governments, and global security. While these developments offer real opportunities, they also raise serious concerns about ethics, accountability, and regulation. At the same time, the international system is moving toward a more multipolar balance of power. Traditional centers of influence are being challenged as new actors gain greater voice on the global stage. This shift brings the potential for cooperation, but also the risk of heightened competition and instability. In this environment, the G20 has a critical role in encouraging dialogue and coordinated action. By addressing AI governance alongside evolving power dynamics, the G20 can help guide the international community toward a more stable and inclusive future.
