Inter-Asia Research Networksresult of its connection with international trade routes, Dvaravati culture invaded into northeast Thailand where a lot of moated villages were distributed, especially along the Upper Mun basin. Many Dvaravati-style potsherds, sema stones, stone pestles, and querns have been found in the villages. Dvaravati culture crossed the Mekong and entered Laos as well; Dvaravati-style sema stones were distributed along the east bank of the Mekong. I confirmed the sighting of many sema stones at Ban Na Nga north of Vientiane, and Ban Na Muang, Ban Si Khai, Ban Khan, and other villages in Savanakhet province.Dvaravati cities had three types of city plans. Type A was a city developed from a rural village; these were moated villages with free plans and were distributed in the northeast. Type B was an en-larged city developed from a local village, originally a rural village. These were supply centers of forest products on the trade routes between the ports on the coast and the northeast. As the trade became more active and the population grew, they had to expand their city areas. The expanded area was usually rectangular, influenced by Indian city planning. Type C was a port polity along the coast of the Gulf of Thailand. These were constructed as import-export bases for the international trade. Their city plans were also roughly rectangular, influenced by Indian city planning.
