National Security Council secretary-general Anusit Kunakorn will lead a delegation to China on Wednesday to check the condition of the 109 Uighurs deported there last week.
The trip, which lasts through Friday, comes amid international criticism over Thailand's repatriation of the minority Muslims despite assertions they would be persecuted.
Besides ensuring that the Uighurs are being treated fairly, Mr Anusit said the NSC delegation would discuss with diplomatic and security officials the "ongoing stream of misconception and misunderstanding" surrounding the deportations.
Mr Anusit reiterated that Thailand did not rush to deport the Uighurs, noting they had been in detention camps in the south for more than a year. Officials thoroughly discussed issues related to international law before carrying out their repatriation. He added that the Thai delegates would ask Beijing to help explain that to the global community.
The two sides would also discuss arrangements to facilitate representatives from international organisations to visit the Uighurs -- now detained in custody by China -- as soon as possible, said the NSC secretary-general said.
On Saturday, The Associated Press cited China's official Xinhua News Agency quoting the Ministry of Public Security saying that the 109 ''illegal immigrants'' had been on their way ''to join jihad'' in Turkey, Syria or Iraq, and that 13 of them had fled China after being implicated in terrorist activities. Another two had escaped detention, according to Xinhua.
The AP reported also said Turkish diplomats in some Southeast Asian countries had facilitated the illegal movement of people.
A total of 180 ethnic Uighur refugees out of a group of more than 350 held in Thailand since early year have now been sent to Turkey, while more than 100 have been deported to China amid cncerns from activists they would face detention or torture there.
Another 52 remain in Thailand while their nationalities are being verified.
