In Burma, opposition and human rights groups today will begin talks between pro-democracy leader Aung San Suu Kyi and Burma’s military rulers. A senior Suu Kyi colleague said both sides must avoid provocations that could harm the dialogue. The United Nations revealed yesterday that the talks had been going on in secret since October. A National League of Democracy executive committee member said, “This is what we’ve been working for. And since it has begun, both sides have to be careful not to do anything to derail the process of confidence building.”
