Indonesian President Megawati Sukarnoputri arrived Sunday in Tokyo for a four-day visit as a state guest, Japanese officials said.

She is slated to meet with Prime Minister Junichiro Koizumi on Tuesday. A meeting with Emperor Akihito and Empress Michiko as well as talks with other ministers and government representatives are also planned.

Megawati is the first Indonesian president to travel to Japan as a state guest since 1968, when then President Suharto visited. She made an unofficial visit as president in 2001 and a private trip in 1989.

According to government sources, Japan and Indonesia are discussing setting up a study panel with the aim of concluding a bilateral free-trade agreement.

The two countries are expected to reach an agreement to set up the panel at the summit between Koizumi and Megawati, the sources said.

Japan already has an FTA with Singapore and has set up working groups to study FTAs with Thailand and the Philippines.

The two leaders are also expected to confirm the resumption of preliminary talks on an investment agreement that were suspended three years ago.

Other regional issues, including the conflict in Aceh, the fight against terrorism and collaboration on the nonproliferation of weapons of mass destruction and fighting drug-smuggling, with reference to North Korea, will also be taken up.
