The Kangnido is one of the oldest "surviving" world maps from East Asia, along with the ("ca". 1398) Chinese "Da Ming Hun Yi Tu". Surviving copies of both the Kangnido and the Da Ming Hun Yi Tu all bear later revisions, and the original, unrevised forms of both maps are uncertain. Nevertheless, the surviving copies of the Kangnido constitute one of the most important materials for reconstructing the original form of the 14th-century Chinese map. As a world map, it reflects the geographic knowledge of China during the Mongol Empire when geographical information about Western countries became available via Islamic geographers.
