Chinese Ambassador to Nepal Zheng Xialing urged the government here to check anti-Beijing activities as he claimed that most Tibetan protesters in Nepal were associated with the 'Tibetan government-in-exile.'

They comprise the "vanguard and main force" of the 'Dalai clique' or supporters of the Tibetan spiritual leader, to achieve their goal of a free Tibet, he told reporters on Wednesday.

Describing the anti-China protests here as "illegal political activities," he charged that Tibetan demonstrators damaged the Chinese embassy building in Kathmandu a few days ago and also beat up those Tibetans who took a different position.

"We hope the government of Nepal adheres to 'one-China' policy and does not allow anti-China forces to operate from here," he said.

"We also hope that the government of Nepal can uphold justice, safeguard the dignity of law and take severe measures to prevent these political organisations from organising and implementing their illegal political activity," he said. Zheng said the government of Nepal should take the responsibility for the safety of the Chinese embassy building in Kathmandu as Anti-China elements were operating in Nepal "camouflaged" as Tibetan protesters and were attempting to "sabotage" relations between the two countries, he said, adding "we should be alert about this."

He also asked the Nepal government to restrict the activities of the "unofficial officials" of the Dalai Lama in Nepal.

The official representative office of the Dalai Lama was closed a few years ago as per the instructions of the Nepal government.
