Pheu Thai MP Weng Tojirakan on Thursday said more than 10,000 red shirts would next week attend the friendly football match in Phnom Penh.
The Thai team will comprise red shirts-turned-Pheu Thai MPs and the Cambodian side will be represented by Cabinet members and ranking officials.
"The friendly match will signal that the two countries have resumed good neighbouring ties," weng said.
He said Thailand and Cambodia would not go back to bickering like what happened under the Abhisit Vejjajiva government.
He was speaking after the Criminal Court approved his petition to travel to Cambodia in two separate trips tomorrow and again next Friday. In the first trip, he would be part of an advance team. The second trip would be to take part in the match.
Three other members of the advance team, Veera Musigapong, Natthawut Saikua and Yoswaris "Jeng Dokjik" Chuklom, had earlier obtained the court permission to travel abroad. Weng's trip was delayed for a day because of incomplete documentation.
