Prime Minister Abhisit Vejjajiva will make an official visit to Cambodia on Friday for bilateral talks, including discussions on the continuing border dispute near Preah Vihear temple and the sea border in the Gulf of Thailand.
It will be hisd first trip to Cambodia since taking office in December.
Mr Abhisit said on Thursday he had to cancel his planned visit to Cambodia on April 18 because of the anti-government riots in Bangkok.
He will meet Cambodian Prime Minister Hun Sen to discuss expansion of bilateral cooperation, such as the construction of roads connecting the two countries, the development of water resources, electricity sales and tourism promotion.
Thailand will offer low-interest loans to Cambodia, and will return seven Khmer artifacts smuggled into Thailand by thieves about 10 years ago and later seized by police, he said.
Mr Abhisit said he will also meet Thai businessmen in Phnom Penh to discuss their problems and try and help them if possible.
