(Adds protest in Nepal)

SHENZHEN, China, May 5 (Reuters) - Envoys of the Dalai Lama and Chinese officials agreed to further contact during a day of talks aimed at mending fences following a wave of unrest that pushed Tibet to centre stage ahead of the 2008 Olympics.

The closed-door meeting on Sunday in the southern city of Shenzhen, near Hong Kong, was the first since an anti-Beijing riot in Lhasa and unrest rocked Tibet and nearby areas in March.

"They (the envoys) have completed their discussion," Thubten Samphel, secretary of the Department of Information of the Tibetan government-in-exile in Dharamsala, India, told Reuters.

"Professor Samdhong Rimpoche described the dialogue as going very well," he said, referring to the prime minister of the self-proclaimed government-in-exile.

The Tibetan riots and protests, which China blames on the Dalai Lama, were the most serious challenge to Chinese rule in the mountainous region for nearly two decades.

They prompted anti-China protests that disrupted the international leg of the Olympic torch relay and led to calls to boycott August's Beijing Games, which in turn triggered counter-protests by Chinese fiercely proud of holding the Games.

"Chinese central government officials and the private representatives of the 14th Dalai Lama agreed to hold another round of contact at an appropriate time," China's official Xinhua news agency said.
