United Nations envoy Ibrahim Gambari has left Burma, after a two-day
visit to prepare for a possible trip by U.N. Secretary-General Ban
Details of Gambari's visit were not disclosed, though it was revealed that he met with Burma's foreign minister, Nyan Win, in the country's administrative capital Naypyidaw.
State television says the two officials discussed plans for Secretary Ban's visit.
Mr. Ban and Gambari have been trying to persuade Burma's military rulers to free all political detainees, including democracy leader Aung San Suu Kyi, who is on trial for allegedly violating the terms of her house arrest.
Gambari did not meet Suu Kyi during this trip, which was his eighth to Burma.
Earlier this week, the U.N. secretary-general said he was looking at the appropriate timing for his own visit.
Mr. Ban is scheduled to go to Japan from June 30 to July 2 and could travel to Burma afterwards.
Gambari will report to the U.N. chief on his Burmese visit before Mr. Ban leaves for Japan.
Mr. Ban's trip would come at a time when the Aung San Suu Kyi trial is approaching a conclusion. She is accused of breaching her house arrest by allowing an uninvited intruder to stay in her home overnight. American John Jettaw swam to her lakeside home in early May. She says she permitted him to rest overnight after he said he was exhausted.
Debbie Stothard, a spokeswoman for the ASEAN network on Burma, a regional human rights group, had urged Gambari to deliver an ultimatum on behalf of the international community to call off the trial and proceed with a democratic dialogue.
