The fledgling OneAsia Tour, a rival to the established Asian Tour, on Thursday added the GS Caltex Maekyung Open to its schedule for 2010, with 10 events now confirmed.
The tournament will be played at the Namseoul Country Club in Seoul from May 6-9.
"The GS Caltex Maekyung Open has been an amazing event in Korea for many, many years, and we are delighted to welcome the event to OneAsia," said OneAsia chief executive Ben Sellenger.
"We applaud the organisers' vision and commitment to transform this tournament, and elite Asian tournament golf, into a globally significant property."
Late last year OneAsia announced it would hold 11 events this year, up from the five played during its inaugural season in 2009, and nine of them were confirmed at the time.
All will have at least one million dollars in prizemoney.
In contrast, the Asian Tour will feature at least 28 tournaments this year.
