The first goal came in the 24th minute when Kim Chaewoon followed it inside the box, sidestepped his marker and placed it in.
The lead was doubled 10 minutes later by Park Jeongin with a deft placement.
Changing over, the match was mainly confined to the midfield.
The easiest chance fell to Korea Republic’s Cheon Seonghoon in injury time but with only the rival goalkeeper to beat he hit the post, and even blasted it into the post off the rebound.
Barely a minute later, Korea Republic scored their third goal with Jeon Wooram netting the ball in.
