YANGON - UN Secretary General Ban Ki-moon is likely to meet Myanmar opposition leader Aung San Suu Kyi during his visit to the country later this week, an official said Wednesday.

“He (Ban Ki-moon) is supposed to meet Aung San Suu Kyi when he arrives here but we cannot definitely tell his schedule,” said an official who requested anonymity.

Ban is scheduled to visit Myanmar Friday and Saturday at the official invitation of the ruling junta.

He is expected to meet the country’s most powerful man, Senior General Than Shwe, head of the State Peace and Development Council, as Myanmar’s junta styles itself, officials said.

Besides Suu Kyi and Than Shwe, Ban also plans to meet with political parties and ethnic groups and travel to the Irrawaddy delta region that was devastated by Cyclone Nargis on May 2-3 last year, killing up to 150,000 people.

Ban last visited Myanmar in May 2008 to hasten international aid to the country, whose military rulers are notoriously paranoid about western interference in their internal affairs.

Ban’s talks with Myanmar’s senior leadership are expected to focus on a plea for the release of all political prisoners including Suu Kyi; resumption of dialogue between the government and opposition; and the need to create conditions conducive to credible elections planned in 2010.

“The secretary general believes that the sooner these issues are addressed, the earlier Myanmar will be able to move towards peace, democracy and prosperity. He looks forward to meeting all key stakeholders to discuss what further assistance the United Nations can offer to that end,” a UN statement said.

The first day of Ban’s visit will coincide with the resumption of the trial of Suu Kyi on charges of violating her house arrest, by allowing a US citizen to swim to her lakeside residence in Yangon.

Suu Kyi’s trial, being held at a special court set up in Yangon’s Insein Prison, is scheduled to resume Friday with testimony from defence witness Khin Moe Moe, an attorney.

The trial began May 11. While the prosecution was allowed to present 14 witnesses in the first week, the defence was initially allowed only one. Later, Khin Moe Moe was permitted to testify.

Critics say the military junta is using the case as a pretext to keep the 1991 Nobel peace laureate in jail during a politically sensitive period, leading up to next year’s general election.

Suu Kyi’s National League for Democracy won the 1990 general election by a landslide but has been blocked from power by Myanmar’s junta for the past 19 years.

The new trial of Suu Kyi, whose most recent six-year house arrest sentence expired May 27, has sparked a chorus of protests from world leaders and statements of concern from its regional allies in the Association of South-East Asian Nations.
