The budget comprises general administrative expenses, support for the council's work and the construction of the new parliament, said Charae Panpruang, who replaced Suvichak Narkwatcharachai under a National Council for Peace and Order (NCPO) order on Friday.
He said he had prepared draft regulations for the council's meetings, which would be similar to those of the House, according to a Thai Rath Online report.
Mr Charae also said he would clamp down on corruption for the sake of transparency.
An NCPO expenditure scrutiny committee on Friday added the construction of the new parliament buildings and the welfare building of the House secretariat to a list of projects it wants to re-examine, saying they are not considered in line with budgetary principles.
Some construction preparation has begun on the 12-billion-baht parliament complex on a riverside site in Kiak Kai in Dusit district of Bangkok. However, there have been lengthy delays in handing over some of the land acquired for the site.
