The Chinese government has treated the Olympics as a historic affirmation of the country's progress and stability. The Dalai Lama has said he supports the Olympics and appealed to Tibetans not to protest during the August 8-24 Games.
But Beijing puts protests over Tibet among its top security worries at the Beijing Games.
The London-based Free Tibet Campaign will urge British athletes at the Games to decry China's presence in Tibet by making a "T for Tibet" hand gesture, the group said in an emailed statement.
The Xinhua report did not explain why the Party spokesman repeated the demands now. But they come ahead of the Group of Eight summit in Japan this week, where world leaders, including U.S. President George W. Bush, may raise restive Tibet with Chinese President Hu Jintao.
The Chinese spokesman said the envoys had "expressed acceptance" of the demands. The "promises and positive response by the Dalai's side" were an "important advance", he said.
But weekend comments from the envoy Lodi Gyari suggested the Dalai Lama's negotiators were far from accepting the premises of China's demands.
Speaking in Dharamsala, the northern Indian site of the Tibetan government-in-exile, Gyari said the talks were marked by personal attacks on the Dalai Lama and it seemed China held them in a bid to ensure no disruptions to the Games.
He also "categorically rejected" Chinese claims that the exiled Tibetan Youth Congress engaged in "violent terror."
The two sides held an earlier round of talks in May, and the Dalai's envoys said they expect another meeting in October.
