The government has ended the curfew in Bangkok and 23 other provinces.
Prime Minister Abhisit Vejjajiva said the decision followed assurances from security forces that they had regained control following recent riots and a deadly crackdown in Bangkok and some other provinces that left 85 dead in the capital.
The curfew, which had been in place since May 19, ended at 4am yesterday.
It was first imposed after many buildings were set on fire after the government launched security operations to disperse the red shirt protesters at the Ratchaprasong intersection on May 19.
Mr Abhisit, however, said the state of emergency which was introduced on April 7 remains in force in Bangkok and the 23 other provinces.
Interior Minister Chavarat Charnvirakul yesterday expressed confidence that security forces can control the political situation, especially in the four hotspot northeastern provinces of Ubon Ratchathani, Udon Thani, Khon Kaen and Mukdahan.
The governors and police chiefs of the four provinces were transferred to inactive posts for allowing the red shirt protesters to torch provincial halls following the dispersal of the rally at Ratchaprasong.
Mr Chavarat said the state of emergency should give security authorities enough power to monitor and maintain a presence in these provinces and the others.
He also said the provincial governors had been ordered to bring reconciliation to their provinces or face punishment.
Meanwhile, Energy Minister Wannarat Channukul said yesterday energy facilities across the country remain on highest security alert despite the end of curfew.
He said that oil refineries, power plants, gas separation plants, oil depots and even petrol stations have been instructed to maintain maximum security.
