Thailand's national security chief says 109 ethnic Uighur refugees who were involuntarily sent back to China from Thailand this month have been treated well since their return.

National Security Council Secretary General Anusit Kunakorn was among five Thai officials who traveled to China last Wednesday, one week after the deportation that sparked international criticism and an attack on the Thai Consulate in Istanbul.

Anusit said Monday that the Uighurs (WEE-gurs) were living in good conditions at a rehabilitation center in Xinjiang province in western China.

The Uighurs are a Turkic-speaking Muslim minority in China's far western Xinjiang region. The group has complained of harsh cultural and religious suppression as well as economic marginalization under Chinese rule.

China has said the Uighurs who were sent back had left the country illegally.
