Thaksinocracy is still alive : Thai FM

"The only problem now is that Thaksinocracy is still alive,'' Kasit said, referring to the term Thaksin's critics use for his allegedly corrupt style of rule.

Cambodia arrested and charged Siwarak Chothipong, a Thai engineer with spying on Wednesday. Kasit The minister said the arrest is nothing more than intimidation with the intention to defame Thailand.

Cambodia has charged Siwarak Chothipong, an engineer of Cambodia Air Traffic Services, for "stealing" the flight information of ex-Thai PM Thaksin Shinawatra and Cambodia's PM Hun Sen.

Cambodian prosecutors alleged that Siwarak stole the information and sent it to Thai embassy's first secretary Kamrob Palawatwichai.

Cambodia on Thursday expelled Kamrob following the accusation that he had executed work in contradiction to his position. He was ordered to leave the country within 48 hours.

Cambodia's appointment of Thaksin as the adviser to Hun Sen and his government has seen the start of the current diplomatic rows between the neighbouring countries. Both have recalled their ambassadors and the first secretaries. Thailand has downgraded relations and reviewed cooperation with and loans given to Cambodia.

Thai Prime Minister Abhisit Vejjajiva said the expulsion of the Thai diplomat was intended to provoke a "violent response'' from his government.

"The Thai government didn't fall for their trick,'' he told reporters in Bangkok before leaving for Singapore to attend Apec Summit and Asean-US Summit.
