Lee's next international meet was the 2007 World Sprint Championship in Vikingskipet, Hamar, five weeks after the Nagano World Cup meet. NRC Handelsblad named him as one of the favourites along with Shani Davis, Pekka Koskela and Erben Wennemars. After the first day, Lee trailed Koskela by 0.075 points, having lost 0.31 seconds on the 500 metres. However, Lee lost less on the second day's 500 metre race, and set Koskela the challenge of repeating his time from Saturday to become World Sprint Champion. Koskela arrived 0.13 seconds too late, leaving Lee as the third South Korean world sprint champion, despite not winning a single distance. His placings were fourth, second, third and second.
