President Pranab Mukherjee recently summoned Foreign Secretary S Jaishankar for a meeting, following the Chinese veto on India joining the elite Nuclear Suppliers Group (NSG) in Seoul. Mukherjee, a former foreign minister, wanted to be briefed on the reasons for India's failure to bring China around. The reason for his curiosity was also heightened by the fact that he had earlier raised the issue of Chinese support for India's NSG ambitions in talks with President Xi Jinping during his visit to that country in May.
