Authors: Titus Kisangau, Rahul S Reddy Kadarpeta, Cynthia Waliaula, Rispah Walumbe  Enhancing capacities in health systems strengthening is critical to achieve sustainable health systems reforms towards Universal health coverage (UHC). Traditional methods for capacity building and knowledge exchange often adopt didactic approaches. They assume that technical requirements are static and the need for tailored solutions is for specified timeframes for policymakers and practitioners. However, the ever-evolving technical obstacles in achieving reform objectives and the diverse spectrum of policymakers engaged in this process challenge such conventional approaches.i   A participatory knowledge production process provides stakeholders with dynamic insights, enhancing their capacity for effective problem-solving and addressing future challenges. Cross-country learning, as a method for knowledge sharing and learning aims to build sustainable capacities among policymakers and practitioners involved in health policy reforms within the low- and middle- income country context. This approach recognizes various trajectories associated with achieving sustainable reform, acknowledging the contextual variations and shared elements across countries.  This blog delves into the practical insights from countries into the application of diverse cross- country learning approaches for countries from the global south. This presents a synthesis of the discussions held during the 77th World Health Assembly 2024 – Side session “South-South Collaboration – Harnessing Cross-Country Learning for Sustainable Health System Policy Reform” organized by Joint Learning network for Universal Health Coverage (JLN) and UHC Delivery lab anchored by Amref Health Africa on 27 May 2024, Geneva. The session attracted attendance of 100 global health leaders and public policy practitioners drawn from Ministers of health, policymakers, global health experts drawn from various development partners/ organizations  exploring novel ideas for investments, NGOs, Civil society organizations, researchers and academia convened to examine south-south partnerships as an enabler of enduring reforms in national systems.
