Thailand's foreign minister told reporters on the sidelines of the ASEAN meeting that jailed Myanmar leader Aung San Suu Kyi is healthy told him she encouraged renewed talks to solve the Myanmar crisis.

"There was a meeting, she was in good health and it was a good meeting," Don Pramudwinai said on the sidelines of a meeting of Southeast Asian foreign ministers in the Indonesian capital Jakarta, confirming his private visit to Naypyidaw and his meeting with the Nobel Laureate and democracy icon.

A spokesperson from Thailand's Ministry of Foreign Affairs confirmed the meeting lasted over one hour.

The coup that overthrew Aung San Suu Kyi ended Myanmar's brief democratic experiment and plunged the Southeast Asian nation into bloody turmoil.

The Myanmar leader, 78, was later hit with a raft of charges and jailed by a junta court for a total of 33 years in trials that rights groups slammed as a sham.

Don confirmed that he met with Suu Kyi on Sunday and that she had called for renewed talks to end the crisis, noting: "She encouraged dialogue.”

The ASEAN meeting has been dominated by the Myanmar crisis, which has left the bloc divided about how and whether it should re-engage with Myanmar's junta rulers, who have been barred from its high-level meetings.

Don said he was advocating for "engagement with the authority in Naypyidaw".

"Obviously, we are trying to find a way to settle Myanmar. After two years, there's a development and that should be... positive," he told reporters.

The Myanmar junta has rebuffed repeated requests by foreign diplomats to meet with Aung San Suu Kyi, and for much of her trial, her lawyers were barred from speaking to the media.

In June last year, she was transferred from house arrest in Naypyidaw to solitary confinement in prison.

- One-day visit –

Don "visited here just for a day trip and met with the commander in chief" Min Aung Hlaing, a senior military official told AFP on condition of anonymity.

"I didn't know about any meeting with Daw Aung San Suu Kyi," he said, using a Burmese honorific and without detailing when Don had visited Myanmar.

The military has cited alleged widespread voter fraud during elections in November 2020, which were won resoundingly by Suu Kyi's National League for Democracy, as a reason for its coup, which sparked huge protests and a bloody crackdown.

International observers said at the time that the polls were largely free and fair.

The NLD was decimated by the coup, with many senior members jailed or sent into hiding.
