Relations between Beijing and London were set to deteriorate further after Prime Minister Tony Blair met Tibet's spiritual leader, the Dalai Lama. The Dalai Lama, who was yesterday welcomed by MPs in Parliament, described his first meeting with Mr Blair as 'very happy, very jovial'. They had discussed humanitarian issues. The Dalai Lama said he had explained his quest to promote humanitarian values to Mr Blair, who had shown keen interest. 'He was concerned and sympathetic about Tibetan issues,' the Dalai Lama said. 'I expressed my appreciation and my thanks to him for raising Tibet in his visit to Peking.' A Downing Street spokesman said Monday's 25-minute meeting was purely private and could not reveal what issues were discussed. But a source close to the meeting said the two men discussed human rights issues and the situation in Tibet. They also discussed the possibility of opening a dialogue between Beijing and Tibetan leaders, the source said. A representative of the Archbishop of Canterbury was present at the meeting in a move intended to satisfy Beijing that the Dalai Lama had been invited to Downing Street purely in his capacity as a spiritual leader. At a press conference held by the all-party parliamentary group for Tibet yesterday, the Dalai Lama said he was in the unusual position of agreeing with Beijing - over its opposition to Nato's air offensive in Yugoslavia. He would not say if recent events in Yugoslavia had been raised in discussions with Mr Blair. On Monday, Junior Foreign Minister Baroness Symons told the House of Lords that Britain was continuing to urge Beijing, the Tibetans and the exiled Dalai Lama to enter into negotiations. 'The best way to achieve a lasting solution is by the dialogue between the Chinese Government and the Tibetans and the Dalai Lama, without pre-existing conditions,' Baroness Symons said.
