The Unification Flag is a flag designed to represent all of Korea when North and South Korea participate as one team in sporting events. The flag represents a united Korea (both North and South). The background is white. In the center there is a blue silhouette of the Korean peninsula, including the island of Jeju-do to the southwest and Liancourt Rocks to the east, added in 2006. The flag has no status as an official flag in either country.
Other occasions on which the flag were used include the following:
The flag was prominently displayed at the border between the two sides when the ROK president, Roh Moo-hyun, walked into the DPRK on an official visit in 2007.
A large group of DPRK citizens and officials waved the flag when saying goodbye to Mr. Ro Su Hui, vice-chairman of the Reunification of the Fatherland Union (Pomminryon). This was on the occasion of his return to the ROK from the DPRK by crossing the DMZ line. Media reports referred to the flag as the “Korea is one” flag.  He was immediately arrested upon his return to the ROK and later jailed.
