In the men's team event, Lee dominated the opponents he faced in the tourney, completing all three matches less than 30 minutes and allowing only seven points in the semifinals and eight in the final.

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.

He defeated Chetan Anand, Jan Fröhlich, Eric Pang and Chen Jin before losing to Bao Chunlai of China in the semifinals.

He participated in the Beijing Olympics, where he reached the semi-finals before being defeated by world number one, Lee Chong Wei from Malaysia, and then being beaten by Chen Jin of China in the bronze-medal playoff.
