Khlong Yai

Khlong Yai (Thai: คลองใหญ่, pronounced kʰlɔ̄ːŋ jàj) is a district (Amphoe) of Trat Province, eastern Thailand.

A border crossing into Cambodia is at Hat Lek, known as the Cham Yeam crossing in Koh Kong Province of Cambodia. The nearest Cambodian city is Koh Kong.

History

In the past the area was a part of Patchanta Khiri Khet province (now Koh Kong). Unlike the other parts of Koh Kong, this area became part of Siam (Thailand) by the French-Siamese contract in the reign of King Chulalongkorn, in which Siam had to cede the areas east of the Mekong River and provinces of western Cambodia like Battambang, Siam Nakhon, and Sisophon.

It was made a minor district (king amphoe) in 1912 and officially upgraded to a full district in 1959.
