Myanmar's foreign minister visited Thailand on Wednesday, a Thai government source said, in the first visit abroad by a senior Myanmar official since the military seized power in a coup early this month.
Thai Foreign Minister Don Pramudwinai is expected to hold talks with Wunna Maung Lwin. Indonesian Foreign Minister Retno Marsudi, who is also in Thailand, may arrange to meet with him separately, the source said.
Wunna Maung Lwin was appointed by the military to replace Aung San Suu Kyi as foreign minister.
Agence France-Presse reported on Wednesday Retno may visit to help find a solution, but she had no plans for an immediate trip.
The statement came after a leaked Myanmar government document showed Indonesia's foreign minister Retno Marsudi was to visit the coup-hit nation on Thursday.
The trip was not confirmed by Indonesia -- a key diplomatic player among Southeast Asian nations -- and it said Wednesday that no visit had been scheduled.
But it left open the possibility of a later trip by Marsudi, who was still expected to visit Myanmar for a special meeting of foreign ministers from the Association of Southeast Asian Nations (ASEAN).
The timing of that meeting has yet to be announced.
"After taking into account current developments and following the observations of a number of ASEAN countries, this is not the ideal time to conduct a visit to Myanmar," foreign ministry spokesman Teuku Faizasyah told reporters in Jakarta.
"(But) Indonesia is also committed to keep communicating with all parties in Myanmar."
Faizasyah later told AFP: "We're open to the visit as an option, but we have to carefully decide (its timing)".
