U.N. special envoy Ibrahim Gambari arrived in Myanmar’s capital Monday on a five-day mission to promote national reconciliation and political reform in the military-ruled country.

It is Gambari’s fourth trip to the Southeast Asian country since a deadly crackdown on anti-government protesters last September sparked a global outcry.

It was not immediately known whether he would meet detained democracy leader Aung San Suu Kyi or senior members of the ruling junta.

Suu Kyi’s opposition National League for Democracy hopes the visit will kickstart stalled talks between democratic forces and the military.

The United Nations-brokered talks between a junta-appointed minister, Aung Kyi, and Suu Kyi, who remains under house arrest, began in October 2007 but stopped in January after five meetings.

NLD spokesman Nyan Win said the party will also tell the U.N. envoy to urge the ruling generals to allow regular medical check ups for Suu Kyi, whose personal physician was allowed to see her Sunday.

The Nobel Peace Prize laureate, who had her last medical check up in January, has been held under house arrest for more than 12 of the last 19 years.

Nyan Win said the party will also complain to Gambari that more than 100 of its members have been arrested since the September crackdown, including recent detentions across the country.

Gambari last visited Myanmar in March, a trip he described as a disappointment. Although he was allowed to meet Suu Kyi, he did not see senior junta leaders.

The military has ruled the Southeast Asian nation since 1962 and has been widely criticized for suppressing basic freedoms and human rights.
