Describing Tibet as part of China, US President Barack Obama on Tuesday supported the early resumption of talks between Beijing and representatives of the exiled Tibetan spiritual leader Dalai Lama. Obama said this after his meeting with Chinese counterpart Hu Jintao in Beijing. The last formal talks between the Dalai Lama's envoys and Chinese officials, the seventh since 2002, ended in an impasse in July last year, with China demanding that he prove that he did not support Tibetan independence. Relations have been particularly tense this year after large scale riots in Lhasa, Tibet's capital, in which hundreds of shops were torched and Chinese civilians were attacked.Obama, who is on his maiden state visit to the Communist nation, warned Iran that it faced consequences if it failed to show greater openness on its nuclear programme. He said, Iran has an opportunity to present and demonstrate its peaceful intentions but if it fails to take this opportunity, there will be consequences. The US President said he and Hu want climate change talks in Copenhagen next month to result in a global deal that has immediate operational effect. On North Korea's nuclear weapons programme, Obama said the six-party talks process should resume as soon as possible.
