From the beginning of the 1990's ASEV has been acting as a travel agency. ASEV started to organize and sell trips first to Thailand, then to Laos (1997). In 2007, ASEV expanded its operation in Myanmar (Burma), and a year later, in Cambodia.

 ASEV developed itself when tourism was in its infancy both in Laos and Burma.
In twenty years, the company has acquired of a thorough and exclusive knowledge of theses countries. ASEV offers original tours, some being intended for groups or groups of regrouped individuals or others intended for individual travellers, from trekking trips to cruises, from adventure to quiet discovery, and for the last 5 years, from exploration trips to incentive operations.
