The Suwon Samsung Bluewings say they have agreed to pay the German club (EURO)300,000 ($394,000) for Jong, but declined to say how much they will pay the 27-year-old forward who played for North Korea at the 2010 World Cup.
Bluewings official Lee Ho-seung says Jong had sought the transfer and the negotiations lasted several months.
Jong was born and raised in Japan, but holds a North Korean passport. He will become the fourth such player to join South Korea's K-League, league officials said.
He began his professional career with Japanese club Kawasaki Frontale in 2006 before signing with German second-division club VfL Bochum in 2010 and joining Cologne last year.
