India is hoping to win Japanese backing for a nuclear energy pact during a visit by Prime Minister Narendra Modi, and to lure investment into its $85 billion market while addressing Japan's concerns about doing business with a nuclear armed country.
India has been pushing for an agreement with Japan along the same lines as a 2008 deal with the United States, under which India was allowed to import U.S. nuclear fuel and technology without giving up its military nuclear program.
But Japan wants explicit Indian guarantees not to conduct nuclear tests, and more intrusive inspections of its nuclear facilities, to ensure that spent fuel is not diverted to make bombs.
