2003 Sudirman CupEdit
At the 2003 Sudirman Cup held in Eindhoven, Netherlands, Lee helped his team to win its third Sudirman Cup title, winning all three singles matches. Though lots of great doubles players from South Korea had won numerous international competitions, Team Korea had always struggled to win the Thomas and Sudirman Cup competitions due to the lack of top men's singles players. However, Lee, the winner of the 2003 Swiss Open, showed spectacular performances through the Sudirman Cup tournament, not dropping a single set. In the semifinal, Lee defeated 2001 World Championship runner-up and 2001 All England Open semifinalist Peter Gade 2-0, which led his team to a 3-2 victory over Denmark. Lee won another 2-0 upset victory over world number one ranked Chen Hong in Game 1 of the South Korea's final team event against China.
