President-elect Chen Shui-bian's olive branch has failed to win favour with Beijing, with an authoritative think-tank branding his friendly gestures as another gimmick to cheat the public. A mainland Taiwan affairs expert said Beijing would like to see further concessions from Mr Chen. The president-elect yesterday agreed to Beijing's demand to discuss the 'one China' policy, providing that 'one China' was not a 'principle' but a subject for discussion. The mainland expert described Mr Chen's proposals, including an offer of a peace summit, as tricks to mislead the Taiwan public and international media. 'The 'one China' principle is the core difference between Mr Chen and Beijing and the key obstacle in cross-strait relations,' said Xu Shiuan, director of the mainland's Institute of Taiwan Studies at the Chinese Academy of Social Sciences. 'A significant gap remains between the two sides since so far Mr Chen has only agreed to discuss 'one China' but not to embrace 'one China' as a principle for cross-strait dialogue. 'Now is not the time for Mr Chen to visit the mainland. We will not take the risk of having Mr Chen coming here and chanting 'a thousand years' longevity for Taiwan independence',' Mr Xu, a former senior official of the People's Daily newspaper said. 'Mr Chen aims at putting the ball in the mainland court. If we do not accept his 'olive branch', he can say Beijing should take all the blame. 'Now it is 5pm. If Mr Chen agrees to the 'one China' principle, he can be in Beijing at 7pm. It takes 1.5 hours to fly here from Taipei.' Mr Xu said Beijing was still interested in talking to Mr Chen but would like to see more concessions. The analyst said it was unlikely the mainland would take military action at this stage because Beijing believed most Taiwanese did not support immediate independence. 'We do not see a need for military action at this stage as there is no immediate push to independence,' he said.
