Vienna, July 18: Lobbying for the Indo-US nuclear deal, India on Friday briefed the IAEA board of governors and some NSG countries on the safeguards agreement amid reports there was no sign of opposition to the accord. After discussing with IAEA chief Mohamed ElBaradei the text of the India-specific safeguards accord, foreign secretary Shivshankar Menon told the representatives of 54 countries that the text was a good one. Among the 35 members of the IAEA board of governors, 26 are also part of the Nuclear Suppliers' Group. The remaining 19 NSG countries were also invited for the special briefing held at a venue outside the premises of the IAEA Secretariat in the run-up to the IAEA board's scheduled meeting in Vienna on August 1 to consider the safeguards text for approval. Approval of the India-specific safeguards agreement by the IAEA board is an important step in the operationalisation of the nuclear deal. The briefing, which was a closed-door affair, significantly coincided with the third anniversary of the July 18, 2005 India-US civil nuclear understanding. At the briefing, some factual and technical issues were raised by the delegates. Mr Menon is understood to have allayed apprehensions about the fallout of the pact on the nuclear non-proliferation regime. Mr ElBaradei, a strong advocate of the deal, also met US undersecretary of state William Burns for talks on the nuke accord. Mr Burns, the third-ranking US diplomat, was despatched by the Bush administration for "consultations" on the nuke pact in an attempt to push the deal. Mr Menon's meeting with Mr ElBaradei ahead of the special briefing was considered significant because the IAEA chief has endorsed the nuclear deal as a boost for non-proliferation and peaceful use of relatively clean nuclear energy in the developing world. At the briefing, Mr Menon is understood to have highlighted the importance of the Indo-US nuclear deal initiative while citing the country's impeccable track record on non-proliferation front despite not being a signatory to NPT. The briefing of the IAEA board and NSG members by Mr Menon along with Department of Atomic Energy secretary R.B. Grover is crucial as the board will meet on August 1 to consider approval of the India-specific safeguards agreement initialed on July 7. After the IAEA's approval, India and the US must win clearance from the NSG.
