"Tibet is a very ticklish issue... We have to proceed rather cautiously in regard to it and we do not want it stated that we have been addressing the Chinese Government on this subject. They are sensitive and this itself might create an undesirable reaction in them... For some time past, I have been asked questions about Tibet at press conferences. I have answered them rather vaguely and tried to avoid any direct commitment... We do not intend to make any such clear declaration because whatever we say may be embarrassing either from a Chinese or a Tibetan point of view. Anything we say to the Chinese loses its effect to some extent if any public reference is made to it."
