About 300 Chinese people are fighting alongside the Islamic State in Iraq and Syria, a Chinese state-run newspaper said on Monday, a rare tally that is likely to fuel worry in China that militants pose a threat to security.

China has expressed concern about the rise of Islamic State in the Middle East, nervous about the effect it could have on its Xinjiang region. But it has also shown no sign of wanting to join U.S. efforts to use military force against the group.

Chinese members of the East Turkestan Islamic Movement are traveling to Syria via Turkey to join the Islamic State, also known as IS, the Global Times, a tabloid run by China's ruling Communist Party's official newspaper, the People's Daily, said.
