Yangon  - United Nations special envoy Ibrahim Gambari on Monday met Myanmar opposition leader Aung San Suu Kyi at a government guesthouse in Yangon, official sources said.

The meeting lasted about one hour and 20 minutes, witnesses said. The content of the talks was not immediately revealed but should be disclosed later Monday when Gambari was scheduled to meet with members of Suu Kyi's National League for Democracy, Myanmar's main opposition party.

Gambari, who arrived in Yangon Saturday, is in Myanmar to push for a political dialogue between the ruling junta and Suu Kyi, who has been under house arrest since May 2003.

On his last trip in August, Suu Kyi refused to see Gambari on the grounds that he had failed to meet with the country's military supremo, Senior General Than Shwe, Myanmar's prime decision-maker.

It was still unclear Monday whether Gambari would be granted an interview with Than Shwe on his current trip.

Informed sources said Gambari's trip might be designed to test the waters for a potential visit by UN Secretary General Ban Ki-moon.

Gambari was also scheduled to visit parts of the Irrawaddy Delta, which was devastated by Cyclone Nargis in May.

The cyclone left 140,000 dead or missing and 2.4 million in dire need of emergency assistance, the delivery of which was initially hampered by the military but finally allowed in. (dpa)
