The deal, initiated in 2005, took several years to craft, and was signed by the UPA government headed by Manmohan Singh in 2007.
Jaishankar's appointment as foreign secretary in January 2015 evoked a sharp reaction from various quarters over the timing of the government's decision to remove Sujatha Singh.
He had earlier served as India's Ambassador to the US and before that to China.
A 1977-batch IFS officer, Jaishankar played a key role in resolving the crisis following the incursion in Ladakh's Depsang and the Doklam stand-off, handling the tough negotiations with Beijing.
Among other positions, Jaishankar has been India's High Commissioner to Singapore and Ambassador to the Czech Republic.
