Abstract

This includes the development of border markets between Thailand and Lao PDR along a major route from Chiangkong district-Chiangria through HuayXai district-Lao PDR. Regarding the completed Friendship Bridge IV, there are some advantages and disadvantages affecting to the surrounding communities of those countries. For example, it accomplishes the transportation networks among Thailand, Lao PDR and China.
