The Dalai Lama has called on China's leaders to show greater transparency, in a speech marking the anniversary of the 1959 Tibetan uprising.
The exiled Tibetan spiritual leader said China needed to show freedom of expression and freedom of the press to earn the world's respect and trust.
The Dalai Lama also said he would begin the process of devolving authority to an elected leader.
He was speaking at Dharamsala, the Indian town that has become his base.
"China, with the world's largest population, is an emerging world power and I admire the economic development it has made," he said.
"It also has huge potential to contribute to human progress and world peace. But to do that, China must earn the international community's respect and trust. In order to earn such respect China's leaders must develop greater transparency, their actions corresponding to their words. To ensure this, freedom of expression and freedom of the press are essential."
The Dalai Lama said he would begin the process of devolving authority at a session of the Tibetan parliament-in-exile that begins on 14 March.
"As early as the 1960s, I have repeatedly stressed that Tibetans need a leader, elected freely by the Tibetan people, to whom I can devolve power. Now, we have clearly reached the time to put this into effect," he said.
The Dalai Lama, who heads Tibet's exiled government, has lived in Dharamsala since fleeing across the Himalayas following the failed 1959 uprising against Chinese rule.
He has said he does not want independence for Tibet, only meaningful autonomy.
The Dalai Lama is routinely vilified by the Chinese authorities.
In the run up to the anniversary, police in the Indian capital Delhi detained more than 30 Tibetan exiles protesting outside the Chinese embassy on Wednesday.
The protesters wore yellow T-shirts and waved red and blue Tibetan flags, chanting "Free Tibet" and "We want freedom".
Chinese officials have recently announced travel restrictions to Tibet ahead of the third anniversary of riots there.
In March 2008, Tibet witnessed a wave of violent anti-China protests - the worst unrest there for 20 years.
Beijing blamed the unrest on followers of the Dalai Lama, who it said were seeking to separate Tibet from China.
China responded to the unrest with a massive military crackdown.
Many Tibetans have complained about the growing domination of China's majority Han population in Tibet and accuse the government of trying to dilute their culture.
