Jakarta  - Indonesia condemned a Myanmar court verdict against opposition leader Aung San Suu Kyi and her sentence of house detention handed down ahead of an election, media reports said Wednesday.

"The long imprisonment seems to be intended for effectively preventing Aung San Suu Kyi from participating in the general elections to be held next year," the state-run Antara news agency quoted Foreign Affairs Ministry spokesman Teuku Faizasyah as saying.

He added that the "sentence seems clumsy and unfair" because it stems from a violation of Suu Kyi's previous house detention by an uninvited US national. The police responsible for enforcing that detention and, therefore, responsible for its violation have not faced legal repercussions, he argued.

A Myanmar court on Tuesday handed down a three-year prison term to Suu Kyi, but the head of Myanmar's ruling military junta, Senior General Than Shwe, immediately halved the sentence and said the Nobel Peace Prize laureate, who has spent 14 of the past 20 years in detention, could serve her latest sentence in her Yangon home.

Indonesian lawmaker Theo L Sambuaga of the Golkar Party called on the Indonesian government to urge Myanmar's junta to review the verdict, arguing that the "trumped-up charges" would hurt the image of the Association of South-East Asian Nations, to which both Myanmar and Indonesia belong.

"If Myanmar refuses to review its verdict, there will be a big question over the credibility of next year's election there," The Jakarta Post quoted Sambuaga as saying.

Suu Kyi was arrested in May after US citizen John Yettaw swam to her lakeside home and stayed for two nights.

Yettaw was sentenced to serve seven years with hard labour for violating his tourist visa and swimming in a restricted area. (dpa)
