Non-refoulement is a principle of international law that contains a prohibition for countries to expel or repatriate refugees in any way to a country where their lives are threatened because of race, religion, nationality, membership of certain social groups, or because of their political opinions. This principle has become customary international law, therefore this principle is binding on States parties and countries that are not parties to the 1951 Convention. Indonesia is a country that is not a participant in the 1951 Refugee Convention, so basically Indonesia has no obligation and no authority in the problem of refugees coming to Indonesia. However, Indonesia still complies with jus cogens or customary international law, which is evidenced by Indonesia's willingness to provide temporary protection for refugees who come to Indonesia by not forcibly repatriating refugees to return to their home countries.
