Police found links to international terrorist groups during a raid on an alleged terror camp in China's restive western Muslim region last week, the Foreign Ministry said.
Police said they raided a training camp run by the East Turkestan Islamic Movement, or ETIM, in the mountainous Xinjiang region on Friday, killing 18 suspects and arresting 17 others.
"There is a large amount of evidence that shows, including evidence we got from this raid, that the ETIM is associated with international terrorist forces," said Foreign Ministry spokesman Liu Jianchao on Tuesday.
He also said that the group "planned, organized and carried out a series of violent terrorist activities in China."
Liu gave no specific details about the alleged evidence or attacks and did not say which overseas terror groups those arrested were linked to. China has said before that ETIM has links to al-Qaida.
