South Korea and India have seven points from six matches. Both were joint winners after last year's final was washed out due to heavy rains. The fifth-place play-off match will be held Sunday ahead of the final tie.
South Korea took the lead in the 10th minute after Yoon Sung-Hoon sounded the board from Jeon Byung-Jin's precise pass. Ten minutes later, Britain equalised from a penalty corner converted by Matthew Daly.
Within three minutes, South Korea again nosed ahead when Jeon made a solo run down the left flank and flicked it past the onrushing goalkeeper. You Hyo-Sik converted a penalty corner in the 41st minute to make it 3-1.
