On a January late afternoon I was sitting in a small jungle clearing about 500 meters over the Cambodian border in Laos, utterly lost in a lost world. It was almost completely silent save for the melodious warble of an unseen bird. There is almost nothing which demarcates the international border between Cambodia and Laos along the wild mountains in Virachey National Park save the occasional lone cement post on some of the high peaks that were helicoptered up about 15 years ago. But all of this is about to radically change.
