I recently learned about a meditation center in Cambodia named Phnom Sombok Meditation Centre, about 15 mins outside the town of Kratie ( pronounced Kracheas). It may be related to the Pa-Auk tradition of Myanmar. The teacher is Ven Dhammacari.

There is another new centre near Phnom Penh called Aural Mountain Meditation Centre ( sometimes also spelled Oral), named after its location, but I know little about it.
