Click to play videoWashington: New Delhi and Washington have been unable to overcome the key differences for the final implementation of the Indo-US nuke deal.
Sources say that India has offered to redefine any future nuclear tests in the 123 agreement as a peaceful nuclear explosion in an effort to secure fuel supplies.
Washington however, insists that any such clause is outside the mandate of the agreement approved by the US Congress last year.
Another major obstacle is the mandate that Washington halt all nuclear cooperations if India tests a nuclear weapon as it did in 1998.
And these are some of the issues that Indian Foreign Secretary, Shiv Shankar Menon will try to bridge in his meetings with Nicklous Burns on Tuesday.
Some US experts however, are calling these divisions ominous saying that any final deal will probably not be worked out at least until President George W Bush leaves office in January 2009.
