The Catholic Church in Laos and Cambodia, both former French colonies in Indochina (Southeast Asia), consists solely of an entirely missionary Latin hierarchy, which is joined in a single Episcopal Conference of Laos and Cambodia (French acronym CELAC). There are only pre-diocesan jurisdictions (all exempt, i.e. not part of an ecclesiastical province but directly dependent on the Holy See and its missionary Roman Congregation Propaganda Fide), no single proper see yet :
All defunct jurisdictions have current successors. Formally, there is an Apostolic Nunciature to Cambodia, roughly equivalent to an embassy, and an Apostolic Delegation to Laos, a lower status of representation. These offices are vested, along with the Apostolic Nunciature to Myanmar in the Apostolic Nuncio to Thailand, who resides in Bangkok.
