"All of our people are there reporting that everything seems to be going rather smoothly," Surin told AFP in the Cambodian capitalPhnom Penh, where officials are preparing for a summit of the Association of Southeast Asian Nations (ASEAN).
Voters inMyanmarflocked to the polls on Sunday for elections expected to sweep opposition leader Aung San Suu Kyi into parliament for the first time as part of dramatic political reforms.
Observers from ASEAN were among those invited byMyanmarto monitor the elections.
The milestone polls were marred somewhat by opposition allegations of ballot-paper irregularities, notably that wax had been put over the check box for Suu Kyi's party that could be rubbed off later to cancel the vote.
Surin told AFP he was not aware of this particular complaint.
"I have not heard specific complaints but I understand that overall things are moving well and a lot of those complaints are very common in many elections in many countries too," he said. "So I have not heard anything serious."
Earlier in the day the diplomat told reporters that the ASEAN teams on the ground reported "full enthusiasm, full alert, full awareness of all parties involved in the by-elections".
"It's a good omen forMyanmar," he said.
Myanmar's poor human rights record and iron-fisted suppression of political dissent have often hijacked ASEAN gatherings in the past, much to the embarrassment of more democratic member-states.
