For example, Chiang Rai is the only province that has three airports close by that offer flights to various popular tourist destinations in two neighbouring countries. Travellers touring the region and business travellers building their trade networks do not need to back track to Bangkok to visit Yangon and Vientiane if they are in Chiang Rai.
Relaxed border regulations at Mae Sai allow them to travel freely to most destinations in Myanmar without back-tracking through the same border checkpoint.
