As part of the research project Lifelong learning for ethnic groups in the Greater Mekong Sub-region: Towards culturally responsive development, an expert meeting was organised at the end of January, 2019 at Mahidol University, Thailand. The research project is led by UNESCO International Research and Training Centre for Rural Education (INRULED) and UNESCO Institute for Lifelong Learning (UIL) with the participation of five focal point institutions from five countries, namely Department of Non-formal Education, Cambodia; Yunnan Normal University, China; SEAMEO CED, Lao PDR; RILCA, Thailand; and SEAMEO CELLL, Vietnam. The expected outcomes of this project are five country reports and a synthesis report on government interventions to promote education for ethnic groups, from which policy and practice recommendations as well as lesson sharing can be employed to better educational conditions for such disadvantaged groups. In the expert meeting, focal point institutions were supposed to present the progress of their country reports and challenges that they encountered during researching. Professor Colman Ross, project consultant, together with experienced researchers in the field of ethnic education, provided feedback and suggestions to improve the quality of the country reports. The meeting was productive and of necessity for ensuring all country reports following proper research methodology and aligning with the ultimate goal of the project. Also on this occasion, the hosting institution organised a field trip to Thai Bueng Cultural Tourism Community. Experts and researchers had a chance to witness the full and happy daily life of an examplary ethnic group in Thailand as well as interview the community leader for an in-depth understanding of such successful operations. The international seminar concluded fruitfully in terms of both academic knowledge and real-life experience.
