New York - UN Secretary General Ban Ki-moon plans to visit Japan in late June for talks with government officials and business leaders in that country, a UN spokesperson said Friday.

Ban will be in Tokyo June 30 to July 2 to meet with the prime minister and foreign minister. He will hold a townhall debate with students of the Tokyo University.

His itinerary after Japan is still undecided, but a visit to Myanmar is a "possibility," said Michelle Montas.

Asked whether Ban will go to Myanmar, where the controversial trial of opposition leader Aung San Suu Kyi was still underway, Montas said, "Myanmar is a possibility, but the secretary general has not decided yet."

News reports from Asia quoted Myanmar government officials this week as saying that they have agreed to a request made by Ban for a return visit. Ban visited Yangon and the delta areas devastated by Cyclone Nargis in May 2008.

Ban and many Western governments have called for the release of Suu Kyi since the military government in Yangon began last month the trial, charging her with illegally harbouring a foreigner and violating rules of her house arrest.

The foreigner was an American who had swum to her house, where he was given refuge for two nights.

Suu Kyi heads the National League of Democracy, the main opposition party that has been demanding democratic reform in the impoverished nation governed by the military for more than three decades.(dpa)
