What Martial Arts did Tony Jaa use in Tom Yum Goong (The Protector)?

The thing about Tony Jaa is that he first learned how to do stunt-work watching martial arts films like Enter the Dragon and Shoalin Temple, then he learned sport TKD while he was in training to be a stuntman, then he learned Muay Thai or Muay Boran depending on who tells the story. So in his films you see him using a combination of all those styles, plus anything else he can throw in that looks awesome, it makes for an impressive film and a martial artist who is very impressive in his own right.
