China has requested all nations taking part in this year's G20 summit to submit lists of suspected terrorist organizations as a measure to prevent possible terrorist attacks on the gathering.

The G20 summit is scheduled to take place in the Chinese city of Hangzhou in early September this year. Several world leaders will attend the summit including U.S. President Barack Obama.

"We're facing a grim task in fighting terrorism, and we hope participating countries will work together with Chinese policy to ensure the safety of such large-scale meetings," Hou Le, a senior Chinese counter-terrorism official, told China Daily.

According to the state-run newspaper, the Chinese government has asked local police stations to hand over a list of indigenous terrorist organizations that might pose a security threat to the summit.

Chinese authorities are especially concerned about the activities of the East Turkestan Islamic Movement (ETIM).

ETIM's name cropped up on Chinese media following the recent unrest in the Muslim Uighur community.

China's public security ministry has since expressed concerns that some ETIM members have undergone training in Syria and Afghanistan and could return to China to launch terrorist attacks.

Last year, China introduced several counter-terrorism laws to deal with suspected terrorist organizations like ETIM. These laws have come under scathing criticisms from human right activists and some western countries, who claim that it gives sweeping powers to the Chinese government.
