A senior mainland official in charge of Taiwan affairs yesterday lambasted the island's government for 'sparing no effort in obstructing the cross-strait relations from moving ahead'. Chen Shui-bian's government had 'resorted to every trick' to delay talks between the two sides of the strait, Wang Zaixi , the deputy director of the State Council's Taiwan Affairs Office, told a media forum in Wuhan , Hubei province . 'Due to the pressure from all sides, the Taiwan authorities have no choice but to make a few gestures on some of the cross-strait issues. At the same time, however, [they are] creating different kinds of obstacles for cross-strait consultations,' Mr Wang was quoted by China News Service as saying. 'They have resorted to every trick to cool down the 'mainland fervour' on the island. Because of the impediments by the Taiwanese authorities, there will not be smooth sailing in the personnel as well as economic and cultural exchanges between the two sides of the strait.' The government had continued to pursue activities that would lead to Taiwan's independence, Mr Wang said, calling for vigilance against such moves. But Mr Wang added that Beijing would not retract any of the promises made to the Taiwanese people during earlier visits to the mainland by the opposition leaders. He noted that central government authorities had introduced numerous measures to promote cross-strait exchanges, citing the relaxation of control over mainland tourists to Taiwan, a reduction in university fees for Taiwanese students to the level enjoyed by their mainland counterparts, as well as the continuing efforts to promote direct passenger and freight flights. 'We shall gradually implement each and every one of the promises we made to our compatriots,' Mr Wang said. Meanwhile, upon arriving in Mexico, President Hu Jintao told ethnic Chinese there that all Chinese people needed to be resolute in opposing Taiwanese independence. 'As long as the Chinese compatriots stand firm in opposing Taiwan independence, we will surely be able to defend peace in the Taiwan Strait,' he said. Mr Hu arrived in Mexico on Sunday, for a three-day state visit, where he is expected to sign trade and co-operation accords with Mexican President Vicente Fox. Mr Hu will then travel to New York for a meeting at the United Nations.
