Foreign Minister Kasit Piromya said yesterday he would fully exercise his authority by all means to bring fugitive former Prime Minister Thaksin Shinawatra to justice in Thailand. A group of Thai officials would be dispatched to Dubai next week to inform officials about the Thai Government's concern, as Thaksin regularly used the Gulf state as a base to phone in and provoke his red shirted supporters, he said. Representatives of the Attorney-General's Office were talking with their counterparts in Hong Kong to conclude an extradition treaty, enabling the Government to detain Thaksin if he appeared in the territory, he said. "I speak frankly, this is a struggle between two ideologies. We want democracy, monarchy and constitution but they [Thaksin's group] don't," Kasit told a meeting of the ruling Democrat Party.
