Kaleun people

The Kaleun people (also called Laoeng) are an ethnic group of Thailand and Laos.

The Kaleun are a Tai ethnic group.

However, they may have been descended from Bru people who shifted to a Southwestern Tai language resembling Phuthai and Yoy, as the Vietnamese also refer to the Bru as Ka Leung.

[1] Chamberlain (2016) conjectures that the Kaleun may have originally been Vietic speakers.

[2] The Kaleun typically speak Northeastern Thai as their primary language.
