Vice-President Hu Jintao will set the tone for today's 80th anniversary of the May Fourth Movement with a call emphasising patriotism and nation-building through science, technology and education. In a speech to mark the official celebration at the Great Hall of the People today, Mr Hu is expected to urge young people to forge ahead courageously, selflessly dedicate themselves to the country and devote themselves to the studies of science and technology to increase China's strength. A Beijing source said Mr Hu would call on young people to absorb modern science and to advance technology and their cultural heritage. They should also cultivate correct world views and moral judgments to serve China's modernisation. 'Deng Xiaoping said science and technology were the primary production forces,' Mr Hu would say. Development and stability would also be stressed. Mr Hu's theme is to be reinforced by a gala performance at the Workers' Stadium which will include a chorus of 10,000 young people from universities, government departments and social sectors. The performances, demonstrating the vigour of young people, would serve to remind them to strive to rejuvenate the country and to treasure China's stability and achievements, the source said. Universities were encouraged to restrain their commemorations to academic seminars at which speakers and themes were censored. 'Commemoration activities are allowed but are asked to be carefully monitored,' said Hu Xianzhang, Vice-President of Qinghua University. In a year threatened by rising workers' and rural unrest, and with a calendar featuring the 10th anniversary of the Tiananmen crackdown and the 50th anniversary of the communist state, Beijing leaders have selectively emphasised the patriotic aspects of the May Fourth Movement and kept silent on its democratic aspirations. In an editorial to be published today the Communist Party mouthpiece People's Daily said young people should follow the May Fourth traditions by holding high the 'banner of patriotism and progress'. The paper stressed the importance of science and anti-superstition but said very little on how China should develop democracy.
