Beijing - China on Monday said "serious differences" remained in its dialogue with the exiled Tibetan Buddhist leader, the Dalai Lama, with little sign of progress in the most recent talks.

Talks earlier this month were "frank and sincere" but stalled on the long-standing differences between the two sides, Zhu Weiqu a vice-minister of the ruling Communist Party's United Front Work Department, told reporters.

Zhu accused the Dalai Lama of failing to honour promises made via his envoys at previous talks in July.

The envoys had promised not to support independence for Tibet, violent opposition to Chinese rule, the Indian-based Tibetan Youth Congress or the disruption of the Beijing Olympics, he said.

"They absolutely forgot to carry out their promise and did not stop boycotting and destroying the Beijing Olympics," Zhu said.

"Instead, they intensified sabotaging activities and continued to attack the central government," he said.

Zhu said the Tibetan government-in-exile had supported the Tibetan Youth Congress and other groups advocating independence for Tibet, and had "fanned or organized violent criminal activities."

"They also continued to set up a claim to internationalize the Tibet issue, trying to make use of foreigners in pressuring the central government," he said.

Zhu's remarks follow a statement last week by the two envoys after returning to India, saying they had presented a memorandum to China on "genuine autonomy" for Tibetans in China.

The main purpose of the week-long trip to China was to follow up discussions held in July, said Kasur Lodi Gyari, who led the delegation.

Gyari said the Dalai Lama had advised that further details of the talks should be made public after they were presented at the special general meeting of Tibetan people scheduled to open in Dharamsala on November 17.

The week-long meeting has been called by the Tibetan government-in-exile to decide on the future course of their movement for autonomy.

The Dalai Lama and his government live in exile in the northern Indian hill town.
