With Sui and Luo making par at the hole, Chonlada used a three-wood off the tee, landing about 90 yards out from the green on the left side. With the wind in her face, she hit a near-perfect pitching wedge, landing her ball two yards from the pin. She then made her birdie putt and waited as Seo and Wanchana, playing in the group behind, could only muster par.

"My irons and putts are good today, my shots were good," said Chonlada who earned RMB75,000 for the win. "I was a little nervous because the fairways here are a little bit narrow. This year, I will try to be top 10 in every event."

Other scores saw Thai Pavarisa Yoktuan shoot a tournament low seven-under 65 on the final day to finish in equal sixth with compatriot Wannasiri Sirisampant (70) at four-under 212.

Hwang Ye-nah, the overnight leader from South Korea, ballooned to a three-over 75 to finish in equal eighth with Thai Renuka Suksukont (70).

Prima Thammaraks, the first round co-leader from Thailand, closed with a 73 to finish equal 10th, while China's Shi Yuting struggled to a 75 to sit a shot further back.

Zhao Zhimeng (71) was the top amateur as the Shenzhen teenager finished on one-under 215 in equal 13th place.
