South Korea, victors the first two times the tournament was held in 1956 and 1960, took the lead in the 24th minute at Doha's Al Gharafa Stadium through Koo Ja-cheol.
South Korea enjoyed the best of the second half and went close when Koo Ja-cheol hit the side-netting with a low shot before Lee Yong-rae's free kick flashed narrowly wide of the target.
