In a rare news conference at his embassy, Mr Lu Shumin defended the Chinese military's crackdown on Tibetan protesters that is threatening to disrupt this summer's Olympic Games in Beijing.
'The Dalai Lama has presented himself to be a peaceful, angel like figure, for such a long time,' Mr Lu said. 'If you look at what the Dalai Lama is, what Tibet was like before 1959, you will find out really what Dalai Lama was and still is.' Mr Lu also likened Tibet's traditional governance to Nazi Germany.
He claimed that prior to China's takeover, Tibet resembled 'medieval Europe' and cited a 1939 trip to the mountainous enclave by a Nazi official who, Mr Lu said, found much in common with the Tibetan system of governance.
Mr Lu's comments came the same day that US President George W. Bush expressed concern about Tibet - which has been racked by violent anti-Chinese protests this month - in a phone call to Chinese President Hu Jintao.
Chinese authorities claim the Dalai Lama's followers orchestrated the violence that broke out on March 14 following a series of protests in Tibet's capital, Lhasa. World leaders have condemned China's ensuing crackdown on the protests.
Canada's prime minister urged China last week to show restraint in dealing with the uprising, and asked that Beijing listen to the Dalai Lama - Tibet's spiritual leader and a 1989 Nobel Peace Prize laureate who has been calling for peace and reconciliation.
But Lu countered that the Dalai Lama 'has been telling lies to the world for decades,' and chastised interference by foreign leaders.
'Any remarks made accusing China of so called human rights suppression, I consider that irresponsible and inappropriate and it's interference in China's internal issues,' the ambassador said.
The diplomat showed journalists a video he said portrayed violent street demonstrations in the Tibetan capital of Lhasa that had to be suppressed.
'He advocates for so called peaceful demonstrations, non violence,' Mr Lu said. 'Do you see anything he has done in that direction? The videotape here showed clearly what is happening in Tibet was instigated by this separatist groups led by Dalai clique.' But Mr Dermot Travis, executive director of the Canada Tibet Committee, said China has no way of proving its version of events.
'One of the things the Dalai Lama has requested, and what we've requested, is a UN team to investigate and report on the situation in Tibet,' Mr Travis said.
Mr Lu said Chinese government is open to dialogue with the Dalai Lama 'as long as he gives up his idea of Tibet independence' and recognises that Tibet and Taiwan are a part of China.
Mr Lu shrugged off talk that some government officials from western countries could boycott the Olympic opening ceremonies because of the crackdown, and said that politicising the Games goes against the Olympic spirit and should not happen.
Relations between China and Canada were damaged in 2006 when Canada granted the Dalai Lama honorary Canadian citizenship.
China also criticised a 2007 public meeting between Prime Minister Stephen Harper and the Dalai Lama as 'gross interference' with its internal affairs. The meeting was the first between a Canadian prime minister and Tibet's exiled spiritual leader in federal government offices. -- AP
