The scrapped projects are what is left of the One Tablet per Child programme and a diesel train engine repair venture.
The committee also ordered a review of the advance passenger processing system proposed by Airports of Thailand, and the Energy Conservation Fund.
The remaining four projects are still being considered: Suvarnabhumi airport expansion phase 2, 3G expansion by TOT, new engine purchases by the State Railway of Thailand, and discount coupons for digital TV set-top boxes by the National Broadcasting and Telecommunications Commission.
A public hearing will be held on each of these projects. If they are transparent, they may proceed in September, officials said.
The panel also chose another two projects to look into: the construction of a new parliament and the welfare building of the House secretariat, as 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.
