The Economic Quadrangle Cooperation (EQC) was initially established to encourage market links by taking advantage of border areas in Myanma, Laos, China, and Thailand. The aim in forming the EQC was to formalize and develop existing cross-border trade, tourism and transport links among member countries. Concerning transport links, the road connecting Mae Sai (Thailand), Tachilek (Maynmar). Keng Tung (Myanmar), Mongla (Myanmar), and Da Luo (China) is considered as the strategic route to encourage project's activities.
