Japan and Russia will sign more than 10 documents during President Vladimir Putin's official visit to Tokyo in early September to boost cooperation in various areas and maintain the momentum toward strengthened bilateral ties, government sources said Monday.

The sources said that among the planned documents will be three new cooperation pacts — one for science and technology, another on cultural exchanges and a third for maritime safety.

The science and technology pact will replace a similar treaty that has existed between the two countries since the Soviet era. The new pact will help promote joint scientific and technological research activities because it, unlike the old one, will provide legal protection of intellectual property rights, the sources said.
