The Dalai Lama said Monday that his approach to Tibet's greater autonomy has so far failed, and that Tibetans should decide for themselves the future direction the region should take.

"My trust in the Chinese government has become thinner, thinner, thinner," he said.

Speaking to a packed room at the Foreign Correspondents' Club of Japan during his weeklong stay in Japan, the Tibetan spiritual leader spoke on topics ranging from politics to ecology, while entertaining an enthusiastic audience with his signature wit and charm.
