Yung spared her last frame and an eight pin count in her bonus frame was good enough to clinch the crown by just a single pin, 212-211.
"I had barely made the tour in 16th position and I was expecting to be knocked out in the first round when I was matched up against a former tour winner," said the 29-year-old former Hong Kong national youth member.
"I'm simply overjoyed to have come away with this victory. I'm now hoping that I can qualify for the grand finals."
Yung dashed Hong Kong national team's hope of winning the women's title when she defeated Chan Shuk Han, 188-168 in the semi-final. Lee sailed past 2011 ABF Tour Macau leg champion, Julia Lam of Macau, 190-144 in the other semi.
Dr Danny Santos, Asian Bowling Federation Vice President and tournament director gave away the prizes to the champions. The next stop will be in Macau, China on June 17 after the Macau China International Open 2012.
