Japanese Prime Minister Yukio Hatoyama arrived in India Sunday on a three-day visit aimed at strengthening economic and security cooperation with the emerging giant.
Hatoyama and a high-level delegation arrived in the financial capital Mumbai.
He will head for the capital New Delhi on Monday for a private dinner with Prime Minister Manmohan Singh, and will also meet with Sonia Gandhi, chief of the ruling Congress Party.
Singh and Hatoyama, who have already met twice in the last three months, will hold a joint press conference Tuesday.
External affairs spokesman Vishnu Prakash said earlier the visit "obviously reflects the continuing commitment of the two sides to strengthening and broadening our bilateral relations."
Hatoyama is also scheduled to meet top Indian business leaders, including chairman of the Tata Group conglomerate Ratan Tata and Mukesh Ambani, head of India's biggest private sector company Reliance Industries Ltd.
Civil nuclear cooperation and defence are among the items on the agenda, with India keen to access Japanese nuclear power technology and both nations having signed a joint declaration on security cooperation last year.
"The two sides...are in the process of concluding discussing a Comprehensive Economic Partnership Agreement (CEPA)," said India's foreign ministry spokesman, Vishnu Prakash. Twelve rounds of talks on the agreement had already taken place, he said.
Japan is India's sixth largest investor. Bilateral trade, more than $12 billion in 2008-09, is targetted to climb to $20 billion by next year.
Hatoyama's talks in India could also focus on on climate change policies -- with the two countries on opposite sides of the debate, particularly on expanding the scope of Japanese support for renewable energy projects in India.
