Taipei accused the mainland yesterday of making false accusations about its dealing with the island on farm trade issues. 'It has been more than a month now, but we have seen no concrete and sincere responses from Beijing. So what Chen Yunlin said was nothing but lies,' said You Ying-lung, spokesman for Taiwan's Mainland Affairs Council. His comments came after Mr Chen, director of the mainland's Taiwan Affairs Office (TAO), said the President Chen Shui-bian government was insincere about dealing with Beijing on farm trade issues. In a meeting with visiting New Party chairman Yok Mu-ming on Sunday in Beijing, the TAO director said Taiwanese authorities had deliberately undermined goodwill extended by Beijing in relation to exports of farm products to the mainland. He said when the mainland expressed its position on cross-strait talks, the Chen government accused it of being 'bossy', and when it extended goodwill, Taipei authorities claimed it was a tactic to woo the Taiwanese people. Mr You rejected Mr Chen's claims, saying Taipei was concerned about agricultural exports to the mainland. 'As early as June 13, we asked the Taiwan External Trade Development Council, which is experienced in the marketing of Taiwanese farm products internationally, to represent the government in talks with [the mainland],' he said. Mr You said Taiwanese authorities had never banned farmers from exporting agricultural products to the mainland, and had long welcomed the exchange of views on the issue of farm trade between civilian groups and Beijing. 'But for matters that involve government power, such as the issuing of certificates of origin and quarantine, talks on these issues must need authorisation from the government,' he said.
