 Due to the limited resources of the Kingdom, Samlout received little government management or support for wildlife enforcement and nature conservation.In 2003, the Maddox Jolie-Pitt Foundation (MJP) began to support the park.On 3 October 2006, MJP, the Cambodian Ministry of Environment and the National Park Service of the United States signed an agreement making the Sequoia and Kings Canyon National Parks "sister parks" to Samlout.
