Various export supporting systems of Korean government have affected Korean economy to be 13th in the world and over US$ seven hundred trillion in terms of the volume. Especially, export insurance system use to cover the commercial risks of Korean exporter. That is why Korean exporter have been able to do their best in exporting and expand overseas market actively. On the other hand, China who use to drive strong export expansion policy after joining WTO, have also very focused on export insurance system and developed its applicable items. From the point of view above, It is very meaningful study to compare the export insurance system between Korea and China. It is suggested that government funds for export insurance should be raised to give exporters more benefits. New kinds of export insurance items, also, should be developed to actively face international trade environment change.
