Mainland students have staged scattered anti-Taiwan independence rallies as government authorities move to rein in their activities, fearing they may get out of control. There were several small-scale anti-Taiwan independence demonstrations on mainland university campuses after Chen Shui-bian won the presidential election on Saturday. Mainland sources said Dongbei Teachers' University in Changchun, Jilin province, and Chongqing University in Sichuan had held rallies condemning Taiwan independence. 'Students from Dongbei Teachers' University came on stage criticising Taiwan independence and urging the Government to take stronger measures curbing the island's independence move,' sources said, adding that student protesters had held placards saying 'anyone pushing for independence is the sinner of history'. Demonstrations were scattered and mostly small, but authorities feared they might gather momentum as students were spreading news of the protests on the Internet. Mainland security authorities had urged university administrators to prevent students from holding street rallies, Beijing sources said. Officials were especially concerned at a protest by students in the capital. 'We have discouraged students from organising demonstrations, but we've held seminars since Saturday to let them voice their opinions on the Taiwan election result,' said Sun Zhe, spokesman for Qinghua University. Students of Beijing University, the centre of pro-democracy student demonstrations, had applied for a permit for anti-independence demonstrations but were turned down, university sources said. Students at the Chinese Academy of Social Sciences acted more rationally as they were mainly doctoral students, the academy's Professor Zhou Dongtao said. 'Authorities are not willing to see students using Taiwan independence as an excuse for organising rallies,' Professor Zhou said.
