The Korea Football Association has sent an official to FIFA headquarters in Zurich to explain why midfielder Park Jong-woo held up a sign asserting Korea's sovereignty over the Dokdo islets after a 2-0 victory over Japan at the London Olympics.

A spokesperson on Wednesday said the KFA has come to the conclusion that a written report to FIFA would be insufficient, so KFA Secretary-General Kim Joo-sung will go in person on Thursday to make it clear that Park's action was not premeditated.

Olympic regulations ban the display of political or religious messages.

The KFA report includes evidence such as photos and a video clip that show a spectator handing over the sign to Park after the match against Japan, which maintains a dubious claim to the islets.

KFA honorary president Chung Mong-joon said he reviewed the documents along with experts in diplomacy and the association will seek close cooperation from FIFA officials. Kim flew to Zurich on Wednesday afternoon to meet the deadline for submission.
