In the aftermath of Siamese–Vietnamese War (1841–1845), the region was part of the Gia Định Province of the Empire of Đại Nam, later it became part of French Cochinchina. In July 1867, the French Cochinchina government ceded part of the Trảng Bàng Inspection (including the Parrot's Beak areas) to the Kingdom of Cambodia under a treaty with King Norodom. The Parrot's Beak is returned to Cambodia under the administration of Svay Theab District.
