Co-sanctioned by the European Tour and the Asian Tour, each tour's No. 1 ranked player - David Howell of England and Charlie Wi of Korea - will be on hand to try and win the event before the tour heads back to continental Europe.
Joining them are defending champion Paul Casey and Paul McGinley, who lost to Casey in a playoff last year. McGinley fired a final-round 9-under 63 to force the extra holes only to fall on the second playoff hole.
The victory was one of two wins for Casey in the 2005 season, both of which came in China.
'I am looking forward to returning to Sanya as it is a course that sets up very well for my game and reminds me a lot of my home course in the UK, The Wisley. I believe they have added a few more bunkers and a couple of new tees for this year's event, and I'm sure the course will be in excellent condition for the tournament,' said Casey on his website.
Howell also has good memories of China as it was just five months ago when the Englishman held off Tiger Woods to win the inaugural HSBC Champions event in Shanghai.
Korea's Wi, who's coming off his win at the Maybank Malaysian Open in February, will be trying to keep his spot atop the Asian Tour intact but will have to fend off the likes of Mardan Mamat, Thongchai Jaidee and China's own Lian-Wei Zhang.
Zhang, who became the first Chinese player to win a European Tour event when he won the Singapore Masters in 2003, will hope to do one better and become the first to win an event on Chinese soil.
Yalong Bay Golf Course is located in the resort of Sanya on Hainan Island, the southern most point of China.
The Golf Channel will broadcast all four rounds beginning Thursday at 9 a.m.
