Envoys of the Dalai Lama ended two days of talks Wednesday with Chinese officials on the future of Tibet, even as their spiritual leader said he saw no hope in the dialogue with Beijing.

Lodi Gyaltsen Gyari, Kelsang Gyaltsen and three aides left for Beijing on October 30 but only began formal discussions on Tuesday, said an official with the Tibetan government-in-exile who asked not to be named.

"The talks were for two days. They began yesterday morning," said an aide in the office of exiled prime minister Samdhong Rinpoche.

The envoys were soon due back in Dharamshala — the Indian hill town seat of the government in exile — from what was the eighth round of a long-running dialogue with China.

During their visit, the envoys were taken to the Muslim autonomous region of Ningxia by Chinese authorities in order to demonstrate Beijing's handling of minority concerns, said the exiled administration's spokesman Thubten Samphel.

The talks came as the Dalai Lama made clear that he had all but given up on the possibility of reaching a mutually acceptable solution to the Tibet issue with the current Beijing administration.

"My trust in the Chinese government has become thinner, thinner, thinner," the Tibetan leader told reporters Monday during a trip to Japan.

"I have to accept failure," he added.

The Dalai Lama has long championed a "middle path" policy with China which espouses "meaningful autonomy" for Tibet, rather than the full independence for the remote Himalayan region that many younger, more radical activists demand.

The future of that policy will be the focus of a special meeting in Dharamshala next month of around 300 delegates representing the worldwide exiled Tibetan community.

The Dalai Lama fled into exile in India in 1959 following a failed uprising in Tibet against Chinese rule.
