List of World Heritage Sites in Thailand

The UNESCO World Heritage Sites are places of importance to cultural or natural heritage as described in the UNESCO World Heritage Convention.
Tentative list.
The following 6 sites are on the tentative list for Thailand, meaning that the government intends to consider them for nomination in the future:
Current status.
In 2005, the Wat Suthat, including the Giant Swing, was proposed as a UNESCO world heritage site.
In July 2015 and July 2016, the Thai Government requested the World Heritage Committee at its 39th and 40th sessions in Bonn, Germany and Istanbul, Turkey to consider the inscription of Kaeng Krachan Forest Complex (KKFC), while IUCN and the World Heritage Committee recognized the outstanding universal value of the site, in 2015, the committee decided to refer the nomination because of concerning on serious human rights violation toward Karen people in the Kaeng Krachan National Park. In 2016, the committee decided to refer the nomination again after received concern from Myanmar Government on unclear border demarcation between Thailand and Myanmar on the western site of Kaeng Krachan National Park.
Thai Government nominated Phu Phra Bat Historical Park in 2016, but decided to withdraw after received recommendation from ICOMOS to redraft the nomination dossier.
In 2018, plans to nominate Si Thep Historical Park to the world heritage list was being planned by various Thai sectors. However, in March 2019, the government announced an oil exploration project to be conducted by the much-criticized Eco Orient Resources Corporation within the buffer zone of the park, effectively destroying any possibility for the site's inclusion in the world heritage list.
