UNESCO has added the Palm-Leaf Manuscripts of Phra That Phanom Chronicle to its prestigious Memory of the World International Register. The decision was made during the 216th session of the Executive Board - Programme and External Relations Commission in Paris, France.

These manuscripts recount the story of Lord Buddha's breast bones being brought from India to Phra That Phanom, a revered Buddhist center in the Mekong region. The collection consists of 10 versions written by different individuals at various times in history, representing a diverse array of palm-leaf manuscripts kept in different areas of Northeast Thailand and the Mid-Mekong region.

These manuscripts hold significant cultural and religious importance, as they reflect the arrival of Buddhism in the Mekong Basins and its integration with local beliefs over centuries.

This recognition marks Thailand's sixth UNESCO-listed documentary heritage item. Additionally, Thailand submitted another nomination, Nanthopananthasut Kham Luang, a Buddhist work, which did not receive inclusion, prompting the government to seek clarification from UNESCO's International Advisory Committee for future proposals.
