To that end, Indonesia assigns the ASEAN Senior Officials Meeting on Youth (SOMY) as the appropriate lead sectoral body to advance the ASEAN CoP and its practical platform for the ASEAN youths to play a significant proactive role in propagating tolerance on religious diversity towards social harmony. With this in mind, it is hoped that the ASEAN Youth Interfaith Camp (AYIC) can give a meaningful contribution in supporting the regional efforts to enhance religious tolerance and the value of moderation at all levels. Furthermore, AYIC may contribute towards alleviating the emergence of new geopolitical, geoeconomics, and geostrategic challenges through its post-event initiatives that have a direct impact towards building community characteristics that is ingrained with tolerance and deference towards religious diversity. In light of the incoming Indonesia’s Chairmanship of ASEAN in 2023, this paper attempts to chart the policy prospect that Indonesia should take in fostering interfaith tolerance and harmony amongst youth across ASEAN so as to support the regional efforts to enhance peaceful co-existence in Southeast Asia. Keywords: ASEAN, Culture of Prevention, Interfaith, Youth I.

In the ASEAN socio-culture front, AYIC is recognized as the ASEAN Senior Officials Meeting on Youth (SOMY) flagship project under its sectoral work plans (2016-2020 and 2021-2025). The initiative is specifically meant to be a platform that propagate tolerance on religious diversity in the ASEAN region. As of 2017, this recurring initiative has brought together young citizens from ASEAN Member States to learn about the importance of fostering greater religious tolerance in light of the rapid spread of disinformation and disruption in social cohesion. The achievement of AYIC is ASEAN youth’s commitment for concrete actions in supporting the realization of a constructive and prosperous ASEAN Community through the enhancement of interfaith dialogue and partnership at both the national and regional level. The inaugural AYIC held in 2017 resulted in the adoption of the Jombang Declaration.(Kementerian Luar Negeri RI, 2017) Two years later, the 3 rd AYIC came up with the adoption of the Lombok Declaration to strengthen the principles contained in the previous Declaration.(Sasongko, 2019) These two deliverables reflected the energy, enthusiasm,
