The Indonesian state has a vested interest in the implementation of international relations as the nation opens up for international cooperation with several countries. This international cooperation will be applied through the ratification of international treaties and conventions. However, one aspect that has so far received less attention in Indonesia is the vague meaning of ratification of international conventions and treaties in Law No. 24/2000 on International Treaties. The purpose of this study is to help understand the ratification concept for a better international cooperation between Indonesia and other countries. This paper seeks to address the question whether there are differences in legal concepts regarding the meaning of ratification and accession according to the 1969 Vienna Convention of and Law No. 24/2000 on International Treaties, which carries out the reciprocity of values or norms regarding ratification and accession that exist in the 1969 Vienna Convention. This study reveals that due to the ambiguity in its meaning, the term accession is not properly applied by the Indonesian government. The study also shows that despite numerous reforms, much Indonesian legal term related to international law remain ambiguous and have multiple interpretations, which leads to confusion and ambiguity.
