The much-awaited talks between the Dalai Lama's envoys and China ended abruptly on Sunday hours after the two sides met for the first time since the unrest erupted in Tibet in March, with Beijing demanding "credible moves" from the the Tibetan leader to stop violence as a precondition for the next round of parleys.

Chinese officials and the Dalai Lama’s “private representatives” agreed to hold another round of “contact and consultation at an appropriate time”, state run Xinhua news agency said after the meeting in the booming southern city of Shenzen.

It said during the meeting officials Zhu Weiqun and Sitar told the Dalai Lama’s envoys that the riots in Lhasa on March 12 had given rise to “new obstacles” for resuming contacts and consultations with the “Dalai side”.

However, the government, they said, still arranged the meeting with “great patience and sincerity”.

Zhu and Sitar had expressed the hope that to create conditions for the next round of contact and consultation, the Dalai side would take “credible moves to stop activities aimed at splitting China, stop plotting and inciting violence and stop disrupting and sabotaging the Beijing Olympic Games”, the agency said quoting sources.

Earlier the Tibetan government-in-exile based in Dharmshala had said talks between the Dalai Lama’s envoys Lody Gyari and Kelsang Gyaltsen and Chinese officials would continue for next two-three days but the parleys failed to stretch beyond a few hours at the tightly guarded state guest house.

Tenzin Takhla, Dalai Lama’s secretary had said on Sunday morning from Dharamshala, that the envoys are expected to return to India by Thursday and brief the Dalai Lama on the talks.

China has repeatedly accused the Dalai Lama of having orchestrated the violence since March during the most sustained anti-government protests in the last two decades that shook the Communist leadership, but the self-exiled spiritual leader has denied the charge.

China, which received flak for its crackdown on Tibetans, agreed to hold talks after sustained international pressure, especially from the West to address the concerns of the Tibetan people ahead of Beijing Olympics in August.
