"Jiegao" is a Dai word, meaning "the old town". It is said that Sinan King of Luchuan built his capital here in the late Yuan Dynasty or the early Ming Dynasty. Thus the town got such a name. During the Anti-Japanese War, Jiegao was a very prosperous town. American planes frequently came here, carrying military supplies. It lies 4 kilometers away from Ruili, and is the only part of Ruili Town on the southeastern bank of the Ruili River, known as "shatoujiao" or "Tianyahaijiao" in the southwest of China.
In 1987 Jiegao became an important port where bilateral trade could be done. In 1991, "Jiegao Border Trade Economic Zone" was set up. China and Burma have built China-Burma Street, which is now filled with stores and shops. Since 1992 the imports and exports from Jiegao have accounted for 50% to 60% of the total imports and exports of the border trade of the province, and over 30% of the imports and exports of the border trade from the inland ports throughout the country. Jiegao Bridge across the Ruili River links Ruili with Jiegao. The bridge is now the longest road bridge in Yunnan and on the boundary line in the Southwest of China. In a word, the booming Jiegao has become a newly- developing business town and border resort with typical ethnic features and modern facilities.
