BEIJING: China's foreign ministry has denounced Lobsang Sangay , the prime minister of Tibet 's government-in-exile calling him a separatist who had never done a good thing in his life.

The statement aims to set the agenda for the coming India-China talks as it comes ahead of Chinese foreign minister Wang Yi's visit to Delhi on June 8, sources said.

"The relevant person is 100% a splittist. He is the ringleader of the so-called Tibetan government-in-exile. He has never done anything good on the Tibet issue ," Hong Lei, Chinese foreign ministry spokesman said.

Barring Chinese request not to allow anti-China movement on Indian soil, both countries have generally skirted the sensitive Tibet issue during their talks. China is now indicating it wants to discuss the presence of the Tibetan government in exile when Wang meets external affairs minister Sushma Swaraj and Prime Minister Narendra Modi.

The body Lobsang leads is illegal under Chinese law as it seeks to separate Tibet from China for the purposes of its independence, and is not recognized by any country, Hong said.

"People can only laugh at the slander he makes about Tibet's situation," he added.

Lobsang recently issued a statement saying he was hopeful Chinese President Xi Jinping would resume formal talks and soften China's handling of Tibet.

Agitating Tibetans say they are not seeking independence but greater autonomy under the Chinese constitution. China says it is an excuse to seek full independence.

"Tibet's independence is not acceptable, nor is half-independence, nor covert independence," Hong said.

Agitating Tibetans in China have been involved in a series of self-immolation incidents resulting in the death of around 130 of them since 2009. China is worried the suicide cases attract world attention and cause loss to its image.
