ABSTRACT
Until Silla was able to firmly resist T'ang's plan to incorporate the peninsula into the empire, it had been the intention of the Chinese to use the last king of Koguryo, Pojang, as their instrument in governing the peninsula. Pojang was to have been given the titles of Governor-General of Liaotung and King of Choson. This plan came to nought, but his son Tongmu was made Governor-General of Andong, an area extending from the Liao River to the Taedong River including the Liaotung Peninsula, but largely confined in the Korean peninsula to the west coast. By the creation of military commanderies in north-east China and the establishment of a viceroyalty in southern Manchuria, the Chinese hoped both to contain the expansion of Manchurian tribal peoples, including the remnants of the Koguryo, and to prevent the northern expansion of Silla (see Fig. 6).
