Seven Thai players, led by Kiradech Aphibarnrat, will try to win the Thailand Classic as the DP World Tour is back in the country for the first time since 2016.
The US$2 million tournament tees off today at Amata Spring Country Club in Chon Buri.
Kiradech, 33, will be chasing his fifth title on the DP World Tour, formerly the European Tour.
The other Thais in the field are eight-time DP World Tour winner Thongchai Jaidee, amateurs Ratchanon 'TK' Chantananuwat and Ashita Piamkulvanich, Arnond Vongvanij, Kwanchai Tannin, and Ekpharit Wu.
Kiradech, affectionately called 'Arm' by the Thai media and fans, is aiming for a home win to complete his recent renaissance and end a five-year title drought.
He claimed his last victory at the 2018 World Super 6 Perth but since then has secured just three top-10 finishes on the DP World Tour after focusing much of his energies on PGA Tour action in the United States.
While he feels there will be some pressure on him at Amata Spring Country Club, Kiradech could not be happier to be back in the country.
"It's really difficult for me to describe how happy I am right now," he said.
"To be practising, playing, in front of my home country, the fans, I really enjoy it.
"The week hasn't started yet. I'm not playing my best the last few years, but so far it's the most happiness I've had in the last two years.
"I'm playing better golf. It's still not the best performance since my first six or seven years on tour, but it's getting there.
"The last six months I've been going in the right direction, working on the swing and at home with my mentality on the golf course.
"I'm playing good and to win in my home country, with home fans would be the best. I really want to win in my home country."
Thongchai, 53, is returning to the DP World Tour from over-50s golf.
The eight-time DP World Tour winner now plays most of his golf on the Champions and Legends Tours, and he is delighted to see young talent, such as 15-year-old Ratchanon, emerging.
"I'm very excited to be back on the DP World Tour in Thailand," he said.
"I played with TK today, he's a good kid. I think good enough to play on tour. I'd love to see the young kids grow up like that and make it to the DP World Tour or the PGA Tour."
Meanwhile, Nicolai Hojgaard will make his debut appearance in Thailand.
The Dane arrives in Thailand reenergised after a one-week break following a busy start to 2023 which saw him play in all four events of the Desert Swing.
"There are many positive trends in the game," he said.
"I'm really looking forward to getting going again after a week off and working on the game. I'm excited for Thursday [today]."
