IUCN Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), 1973. Ensures that international trade in flora and fauna does not threaten the survival of more than 33,000 listed species. PSI is a comprehensive effort to end the trade in weapons of mass destruction, their means of delivery and related materials, as well as to States and non-State actors with proliferation problems. U.S. participation in the PSI, launched on May 31, 2003, is the result of the U.S. National Strategy to Combat Weapons of Mass Destruction issued in December 2002. (DOS website) Treaties concluded at the Council of Europe are multilateral treaties, i.e. they are concluded between more than two States. Only two bilateral treaties have been concluded at the Council of Europe.   A draft convention was initialled by the three countries on April 27, 1914, but China immediately rejected it.   A new convention was signed on July 3, 1914, but only by Great Britain and Tibet.
Chinese plenipotentiary Ivan Chen refused to sign it.   The British and Tibetan plenipotentiaries added a bilateral declaration that the agreement was binding on them and that China would be denied any privileges under the Convention.   Simla was initially rejected by the Indian government as incompatible with the Anglo-Russian Convention of 1907. The official protocol of the treaty, C.U. Aitchison`s A Collection of Treaties, was published stating that no binding agreement had been reached at Simla.  As the condition of the agreement (agreement with China) was not met, the Tibetan government did not approve the McMahon Line.
