Global security is undergoing profound change as new risks and shifting power dynamics reshape the international order. As China's Global Security Initiative marks its fourth anniversary, what role has it played so far? Can cooperation replace confrontation in today's world, and can new ideas deliver real stability on the ground? In this edition of The Hub, Wang Guan speaks with Xia Lu, research fellow at the National Academy of Development and Strategies at Renmin University of China, and Einar Tangen, senior fellow at the Center for International Governance Innovation. Together, they explore how the global security landscape is evolving and assess whether the current international system is weakening. They discuss China's approach to mediation and its role in easing regional tensions, including recent efforts in the Middle East. The panel also looks at what middle power countries can do to chart a principled and pragmatic path to address global and regional security concerns.
