Career
Kim represented North of Korea at the 2008 Summer Olympics in Beijing, where he competed for the men"s extra-lightweight class (60 kg). He defeated Madagascar"s Elie Norbert and Armenia"s Hovhannes Davtyan in the preliminary rounds, before losing out the quarterfinal match, by two yuko and a kata gatame (shoulder hold), to Austria"s Ludwig Paischer. Because his opponent advanced further into the final match, Kim offered another shot for the bronze medal by entering the repechage rounds.
Unfortunately, he finished only in ninth place, after losing out the second repechage bout to Great Britain"s Craig Fallon, who successfully scored a waza-ari (half-point) and a kuchiki taoshi (single leg takedown), at the end of the five-minute period.
