Mr Casey said, ''We continue to encourage the Chinese to engage in dialogue with the Dalai Lama and his representatives. I think that is the most effective way for these issues to be managed in the long term.'' Asked whether he thought China's allegations about suicide plots meant it was refusing all calls to open a dialogue with the Dalai Lama, Casey remarked, ''Well, I hope not.'' ''In the short term we continue to urge the Chinese government to exercise restraint in terms of dealing with any protests that are out there,'' he said The US official praised Dalai Lama as ''an individual who is a man of peace, and someone who supports a nonviolent process of dialogue and discussion to resolve these issues. And hopefully this won't be the last word from the Chinese government with respect to him.''
