South Korean President Lee Myung Bak is planning to visit Japan on from June 28 to 29 to meet Prime Minister Taro Aso as part of their so-called shuttle diplomacy, diplomatic sources said Saturday.

The two countries are also considering holding the summit in Kyoto, with the aim of demonstrating the relaxed nature of their relations by having an informal meeting in a regional sightseeing area rather than in Tokyo, the sources said.

At the talks, Aso is expected to exchange views with Lee on the prospects for the six-party talks on North Korea's nuclear program and repeat Japan's call for South Korea's cooperation in resolving the abduction issue, they said.

Global warming and countermeasures against H1N1 swine flu are also likely to be on the agenda, the sources added.
