Indian Prime Minister Manmohan Singh will travel to Japan on May 27 for a three-day official visit, government sources said in New Delhi.

Singh will be accompanied by a high-level delegation including National Security Adviser Shiv Shankar Menon and Foreign Secretary Ranjan Mathai, the sources said Friday.

Among the issues likely to be discussed during Singh's meetings with Japan's leaders are civil nuclear energy, defense, counterterrorism, disaster management and infrastructure development. Singh is also expected to raise the possible introduction of high-speed shinkansen technology in India.

"All issues of bilateral concern will be taken up in the meetings. The agenda is being drafted and will be formally announced soon," one of the Indian sources said.

India and Japan are fast emerging as allies against China's growing assertiveness in Asia. Both nations have border disputes pending with China and accuse it of intruding into their territory.

New Delhi has accused Beijing of sending a platoon of soldiers across the two countries' disputed border two weeks ago, while Chinese vessels and aircraft have repeatedly intruded into Japan's territorial waters and airspace around the Senkakus after Tokyo effectively nationalized the islets last September.

On Thursday, the two countries held a crucial trilateral meeting — their fourth so far — with the United States in Washington.

Singh's scheduled visit to Japan in November had to be postponed due to domestic political developments, as the Lower House was dissolved that month ahead of the Dec. 16 general election.
