Hosts India beat Myanmar 1-0 on Thursday to set up a final against holders Tajikistan in the AFC Challenge Cup.
Striker Sunil Chhetri headed the winner in the 82nd minute after captain Bhaichung Bhutia neatly chipped over two defenders to the left side of the box in a semi-final played on a water-logged and muddy pitch following heavy rain.
In the second semi-final Tajikistan beat North Korea 1-0. Forward Dzhomikhon Muhidinov headed the first-half winner.
North Korea showed their frustration in the dying minutes when two of their players were sent off for clashing with opponents. The teams were also involved in a minor scuffle at the final whistle.
The winners of the eight-team tournament, in Sunday's final, qualify for the 2011 Asian Cup.
