Sarit Surit, a leader of the former insurgents in Nan province, said that Surayud will meet his group in northern province of Lampang on Friday.
Sarit, said that he would inform the prime minister that they have not yet received what they had been promised when they gave up their fightings under the 66/23 campaign in 1980.
Then governments promised to give several benefits in exchange including lands and assistance for their children's education, Sarit said, but until now they did not get anything.
Surayud's father, Lt Col Payom Chulanont, was a Communist insurgent, was forced to take refuge with the Communist Party of Thailand following a purge of the armed forces led by military strongman Field Marshal Prapas Charusathien.
