Cyclone Nargis pounded the southwest Irrawaddy Delta and the main city of Yangon in early May, leaving more than 133,000 people dead or missing. Inciting international outrage, Myanmar's isolated military regime largely barred foreign aid workers from the delta.
But relief workers slowly moved into the region in late May after the junta began to ease restrictions on access, and asked fellow Asean nations to coordinate the international relief effort.
"We have been able to open the humanitarian space," Surin Pitsuwan told a forum in Singapore of the efforts by the Association of Southeast Asian Nations (Asean).

"I think that's the success of Asean. I think that's the resiliency of Asean. I think that's a new ASEAN ready to take on the responsibility placed on it, expected of it."
Nearly 300 Asean assessment team volunteers were now in the delta, working "with full support, collaboration from the government of Myanmar," said Surin, a former Thai foreign minister.
"It just so happened that we are being baptised by the Cyclone Nargis. That is the test of our new Asean," Surin said.
