Cologne, Germany – Cologne bolstered its attacking options on Se from Bochum for an undisclosed fee.
The team's leading scorer, Lukas Podolski, has been ruled out for a month with a foot injury, making it necessary for Cologne to move for reinforcements.
The 27-year-old Jong joined Bochum in 2010 and has scored 14 goals in 39 league matches for the club since his arrival.
Jong was also a member of North Korea's 2010 World Cup team and has been capped 28 times by his country, scoring 15 goals.
