Now, traces of free trade in the archipelago can not be separated from the past maritime trade activities, especially trade relations with Chinese people. Past trading activity on the east coast of North Sumatera can be traced through the rest of the remains of material culture objects, particularly objects of material culture with respect to trading activities. This can be traced through the remains of material cultural objects found of the site of Kota Cina dan Kompei Island located in the east of North Sumatera.
