I'm know that India does.  I thought the matter had been tabled by the U.N. and had been only tacitly accepted as a consequence of the Cold War.  I thought the U.S. and several other nations had maintained a verbal support of the independence of Tibet but the veto powers of the Soviets as a member of the Security Council had backed China in the matter.  I can't find such a reference. Here is one on the current status: hrw.org
  The following excerpt seems to indicate we did indirectly acknowledge the legitimacy of the Lama ascendency to the throne because when China joined the U.N. THEY told us that Tibet was independent.  This was a backwater then and the world was silent when they were taken over.

  The international relations of Tibet were focused on the country's neighbours. Tibet maintained diplomatic, economic and cultural relations with countries in the region such as Nepal, Bhutan, Sikkim, Mongolia, China, British India, and, to a limited extent, with Russia and Japan.
  Tibet's independent foreign policy is perhaps most obviously demonstrated by the country's neutrality during World War II. Despite strong pressures from Britain, the U.S. and China to allow the passage of military supplies through Tibet to China when Japan blocked the strategically vital "Burma Road," Tibet held fast to its declared neutrality, which the Allies were constrained to respect.
  China today claims that "no country ever recognised Tibet." In international law, recognition can be obtained by an explicit act of recognition or by implicit act or behaviour. The conclusion of treaties, even the conduct of negotiations, and certainly the maintenance of diplomatic relations are forms of recognition. Mongolia and Tibet concluded a formal treaty of recognition in 1913; Nepal not only concluded peace treaties with Tibet, and maintained an Ambassador in Lhasa, but also formally stated to the United Nations in 1949, as part of its application for UN membership, that it maintained independent diplomatic relations with Tibet as it did with several other countries including the United Kingdom, the United States, India and Burma.
  Nepal, Bhutan, Britain, China and India maintained diplomatic missions in Tibet's capital, Lhasa. Although China claimed in its propaganda that its mission in Tibet was a branch office of the so-called Commission of Tibetan and Mongolian Affairs of the Guomindang government, the Tibetan Government only recognised it as a diplomatic mission. Its status was no higher than the Nepalese Embassy (Nepal had a full Ambassador or "Vakil" in Lhasa) or the British Mission. The Tibetan Foreign Office also conducted limited relations with the United States when President Franklin D. Roosevelt sent emissaries to Lhasa to request assistance for the Allied war effort against Japan during the Second World War. Also, during the four UN General assembly debates on Tibet in 1959, 1960, 1961 and 1965, many countries expressly referred to Tibet as an independent country illegally occupied by China. |
