Ahead of negotiations on the bilateral agreement to operationalise the civil nuclear deal with US, India on Saturday made it clear that it would not accept any legal binding on nuclear testing.
"There is no question of signing the Comprehensive Test Ban Treaty (CTBT). We have our voluntary moratorium (on nuclear testing). That position remains," National Security Adviser MK Narayanan told reporters accompanying Prime Minister Manmohan Singh on his three-day visit to the Philippines.
He was asked about US insistence on a legal binding banning nuclear tests and putting a cap on fissile material.
