Kampuchea Krom - Vietnam

The members list of UNPO includes Khmer Kampuchea Krom.

According to UNPO website:

Kampuchea-Krom means "Cambodia Below" or "South Cambodia". Kampuchea-Krom was the southernmost territory of the Khmer Empire, and it was once known as (French) Cochinchina. It is the southwestern part of Vietnam. It covers an area of some 89,000 km2 with Cambodia to the north, the Gulf of Thailand to the west, the South China Sea to the southeast and the Champa's territory to the northeast. [...] It is estimated that there are about 8 million Khmers living in Kampuchea-Krom. Approximately 80 percent of them live in the Mekong delta, and a small number is in other provinces throughout the southern part of Vietnam. Besides the Vietnamese, there are other people living in Kampuchea-Krom, including the Chinese, the Chams, the Mountgards, and many other small ethnic groups. [...] The Khmer Krom are represented in UNPO by the Khmer Kampuchea Krom Federation. The three branches of the federation have been elected from the representatives of Khmer Krom constituencies around the world.

The official Khmer Krom website also shows a logo with these colours.
