China's number one golfer Liang Wenchong will compete in next month's Indonesia Open presented by Enjoy Jakarta along with former winner Thaworn Wiratchant from Thailand, and Singapore' s Mardan Mamat.

The one million U.S. dollars tournament tees-off at Damai Indah Golf - Pantai Indah Kapuk Course from July 1 to 4.

The Indonesia Open is making its debut on OneAsia and is the fifth event on this year's schedule.

Liang has already triumphed on OneAsia this year in the season-opening Luxehills Chengdu Open, where he won in a sudden-death play-off.

It was his second victory on OneAsia as he also claimed the Midea China Classic in 2009 and he says he is looking forward to competing in the Indonesia Open.

"My two victories on OneAsia have both been in China. They were in front of my home fans with great support so I now want to show that I can play at the same level overseas. The Indonesia Open presented by Enjoy Jakarta is one of the most prestigious tournaments in the region with many famous winners so it is a title I would love to win," said Liang.

The 31-year-old, who also claimed the 2008 Hero Honda Indian Open and the Singapore Masters in 2007, is currently ranked 89 in the world.

Thaworn was victorious in the Indonesia Open in 2005 - the year he finished Asia' s number one player. The veteran golfer has claimed 11 titles on the Asian Tour with his last coming in the 2009 Macao Open.

He won Indonesia's national Open by five strokes in 2005 at Cengkareng Golf Club in Jakarta with an amazing four round total of 25-under-par 255.

Mamat has two events to his name in the region most notably, the 2006 Singapore Masters and 2004 Indian Open. His success in India saw him become the first Singaporean to win on the Asian Tour.

Both Thaworn and Mamat will be hoping to join Liang as a winner on OneAsia - which was launched last year to provide leading players in the Asia-Pacific region with an alternative to the PGA Tour and the European Tour.

This season OneAsia has more than doubled in size to 11 tournaments with a total of over 12 million dollars in prize money.
