Since its establishment in 2018, the ASEAN Smart Cities Network (ASCN) has developed into a collaboration platform for city government participation and autonomy. Unlike ASEAN cooperation and partnerships which are generally done at the regional and state level, the ASCN’s new and innovative approach focuses on city level and scalable solutions. ASCN has become a strong basis for external partnerships. Among external partners, The USA, Australia, Japan, China, and the Republic of Korea (ROK) are committed ASCN collaborators.
