On the eve of the Nuclear Suppliers Group's extraordinary plenary meeting to decide on nuclear commerce with India, Foreign Secretary Shiv Shankar Menon will brief the current chair Germany and two other key members of the 45-nation NSG.
Menon, who arrived here today heading a delegation that includes Ravi Grover, Director, Strategic Development of the Department of Atomic Energy, will meet the representatives of the 'Troika' -- Germany, South Africa and Hungary, or the current, previous and upcoming chair of the grouping, the sources said.
Indian envoy to Geneva Venkatesh Verma will accompany Menon during the briefing at the Vienna International Centre this evening, which comes just before the crucial two-day meeting of the NSG to consider a waiver for India, a major step in operationalising the Indo-US nuclear deal.
Earlier, India had briefed NSG members along with the Board of Governors of the International Atomic Energy Agency on July 18 this year and on the sidelines of the NSG meeting in Germany in the month of May.
NSG members and the US envoys are tight-lipped about today's meeting and the officials from Germany told PTI that NSG is a confidential forum and only a press release will be issued after the plenary session that will consider a American draft waiver circulated to members.
According to Indian embassy sources here, the NSG had invited India to be an observer in the two-day discussion which begins tomorrow, but it has been decided to meet the key members before the plenary meeting of NSG.
