The CollAsia international course on “Conserving Photographic and Archival Collections” was successfully held in Ho Chi Minh City, Viet Nam, from 22 November to 15 December 2018. CollAsia is a training partnership between ICCROM and the Cultural Heritage Administration of Korea (CHA) to improve the conservation and use of heritage collections in Southeast Asia. Every year, a course is organized in collaboration with institutions from Member States in the region to address a relevant topic. The courses cover different types of collections and conservation-related skill sets, yet they all promote critical thinking, scientific literacy, applied research, local solutions, and interdisciplinary, value-based, people-centred approaches. Cross-fertilization and synergism within and beyond Southeast Asia are achieved through the participation of heritage professionals from different countries in the region and other parts of the world.
