Prime Minister Manmohan Singh today concluded his 3-day visit to Japan during which the two sides decided to hasten negotiations on a civil nuclear deal and agreed on a range of other issues to take their strategic partnership to new heights. Both the countries also announced the firming up of Comprehensive Economic Partnership Agreement, which will open trade between the two countries and slashing of taxes up to 94 per cent over the next decade. A joint statement issued after talks between Dr Singh and Japanese Prime Minister Naoto Kan in Tokyo yesterday, both the sides noted with satisfaction in rendering the India-Japan CEPA truly comprehensive. It included fields that ranging from trade in goods, investment, trade in services and movement of natural persons to intellectual property and improvement of the business environment. From India's point of view, the CEPA will give a big boost to the country's services sectors, such as information technology, since it would become easier for professionals to move into Japan. It would also help Indian pharmaceuticals gain access to the highly regulated Japanese health market. For Japan, which is grappling with a slowdown, India offers a huge market, with its economy growing in the region of 8.5-9 per cent.Later Dr Singh said, sky is the limit for developing Japan-India relations, a proposition which is close to his heart. Summing up Singh's Japan visit, Foreign Secretary Nirupama Rao said the two Prime Ministers had comprehensive discussions and felt the need for developing all encompassing relations covering political, economy and security aspects. Our correspondent reports that Dr Singh left Tokyo for Malaysian capital Kuala Lumpur this morning on the second leg of his three nation tour that includes Vietnam.
