Korea DPR started promisingly and dominated early possession, but it was the Africans who netted with their first real attack.
Laadi Issaka made a great run down the left, and her low cross found Jane Ayieyam who slotted home from 12 yards for her fifth goal in her sixth U-17 World Cup match.
A few minutes later Sung Hyang Sim had her close-range shot blocked on the line with claims of handball waved away.
Ghana doubled their advantage six minutes into the second stanza with a shocking defensive mix-up between central defender Pak Sin Jong and goalkeeper Kim Myong Sun allowing striker Sandra Owusu Ansah to steal the ball and tap into an empty net.
The goal spurred the Koreans into life. The best passing move of the match resulted in a cross from the left finding Ri Pom Hyang, but she was unable to find a finishing touch under pressure.
Within a minute captain Ri Ji Hyang narrowly pushed a shot wide as Korea DPR found some trademark inner strength and momentum.
The Koreans created several nervous moments around the Ghana penalty area, but few clear chances.
The pace and fluency went out of the game in the latter stages as both teams visibly tired and the physically stronger Ghana always looked likely to hold their lead.
Player of the Match: Sandra Owusu Ansah (Ghana)
