The Dalai Lama expressed confidence he would one day return to Tibet, and called on China's leaders to liberalise to avoid alienating the international community, on a visit to Hungary Monday. 'I'm an optimist, I think I will return to Tibet with a Chinese passport,' the exiled Tibetan spiritual leader told the Hungarian parliament in Budapest on the last day of his four-day visit. Describing China's Tibet policies as 'hardline and rigid,' the 75-year-old Dalai Lama nevertheless pressed that he had 'no ambitions for Tibet to break away from China.' Beijing accuses him of inciting unrest with a hidden pro-independence agenda. 'The Chinese leaders sooner or later have to realise that they must start some sort of politicial liberalisation, or otherwise they will lose the world's trust,' the Dalai Lama told Hungarian MPs. He urged: 'A solution must be found that is good for both China and Tibet.' A decade of dialogue between representatives of the Tibetan leader and China's communist government has failed to reach any substantive progress. The Dalai Lama also noted in his speech, which he gave in English: 'if you are dissatisfied with your politicians you must use freedom of speech to convey your opinion.' During his visit to Hungary -- his sixth in 28 years -- the Dalai Lama held lectures in front of over 20,000 people and was made an honorary citizen of Budapest by Mayor Gabor Demszky. He also met with the 30-member Tibet Parliamentary Group as well as the vice- president of the European Parliament Laszlo Tokes. The Dalai Lama already visited Hungary on six other occasions, the first in 1982, four times in the 1990s and in 2000.
