The Sports Authority of Thailand (SAT) officially signed a deal with MotoGP owners Dorna Sports to hold the race from 2018, according to a statement released by the SAT.
“Signing this contract makes Thailand one of the 19 venues for MotoGP racing... it is provisionally set for first weekend of October next year,” the statement said.
Winter testing will be held February 16-18, it added.
The motorcycling equivalent of Formula One will be staged in Buriram, a small Thai city in the poor rice farming northeast that has seen huge investment in sports and hotel facilities.
Securing MotoGP is a personal coup for Newin Chidchob, a 58-year-old veteran of Thailand’s bear-pit politics, who has pulled in rich contacts to build first-class sports facilities in his home town of Buriram.
In 2014 he unveiled the $58.9 million (B1.95 billion) Formula One-certified circuit in the 30,000 population town.
The Thai junta has agreed to subsidise a chunk of the cost of the rights to host the event.
The motorcycling extravaganza could pour millions of dollars into Buriram, a huge sum for a province that was once among Thailand's poorest.
