Khatoon beat Thailand’s College of Asian Scholars 2-1 in final Group B tie on Saturday.
College of Asian Scholars caught the visitors off guard in the 30th minute with Kurisara Limpawanich delivering a deft through pass to Waenngoen, who beat her marker and the onrushing Yazdani to slot home the opening goal.
Bam Khatoon leveled the score in the 35th minute when Negin Zandi made her way into the box unchallenged before cutting the ball back to Shahnaz Jafari, who squeezed her effort past a stunned College of Asian Scholars keeper Yada Sengyong.
Zahra Ghanbari scored the winner for Bam Khatoon in the stoppage time to seal three points for the Iranian team.
