The Alliance Technical Support Hub in Manila provides technical support to help build community capacity for effective HIV/AIDS responses. It is hosted by PHANSuP's ARETS Asia-Pacific and has a vision of being an enduring platform for developing and sharing expertise. For the Philippines' Global Fund proposal, the hub provided mobilization of resources, technical assistance in proposal writing, and helped ensure an inclusive process with wide consultation. Key success factors included holistic support, community engagement, and timely assistance from experts. Challenges include limited funding for technical support services and enhancing experts' abilities to deliver accessible support.
