The Thai Chamber of Commerce (TCC) announced that state corruption made the recent flooding in Thailand worse than it would have been otherwise. Members of the TCC agreed they would no longer pay bribes to state officials and would closely monitor state projects for corrupt practices. The TCC has also designated Sept 6 as Corruption Suppression Day.

The opposition Democrat Party has also accused the government's Flood Relief Operations Command of corrupt practices and irregularities in its handling of the flood crisis, including its management of donated items and its purchase of bags of relief supplies.
