UNITED NATIONS GROUP OF EXPERTS ON GEOGRAPHICAL NAMES (UNGEGN)
Recognizing the modified general system currently being officially employed in the transcription of geographical names from Thai characters into Roman,
Noting the application of that system for the official bilingual map of Thailand,
Noting further that there is no competing system for the romanization of Thai,
Recommends the adoption of the modified general system of the Royal Institute of Thailand1 as the international system for the romanization of Thai geographical names.
