PARIS, April 9 (Reuter) - Over 200 French parliamentarians, seizing on a controversial official visit by Chinese Premier Li Peng, called on Beijing to pull out of Tibet and said the United Nations should take up the issue.

In a statement issued to coincide with Li Peng's arrival in Paris, the deputies and senators accused China of being responsible for 1.5 million deaths since it occupied Tibet in 1950.

The MPs, of all political affiliations except communists, said China must immediately suspend population transfers in Tibet, end human rights abuses and "start with the process of decolonising Tibet."

They said the mandate of the U.N. Decolonisation Committee should be extended to Tibet, and Beijing should open talks with exiled Tibetan authorities -- who the MPs said were the legitimate representatives of Tibet and should be admitted as observers at the U.N.

The parliamentarians urged the French government and the European Union to intervene with international institutions to support their demands.

A French Foreign Ministry spokesman said France had recognised China's borders in 1964 as including Tibet, but Paris, like its EU partners, was calling for respect of Tibetan culture.

French human rights groups have called for protests during Li Peng's visit.
