External Affairs Minister Subrahmanyam Jaishankar formally joined BJP in presence of working president JP Nadda, at Parliament House.
Jaishankar was appointed as the new external affairs minister on May 31 this year, boosting the confidence on the international front that US-India strategic ties will be further enhanced under his watch.
Jaishankar, 64, known for his skillful diplomacy, tough negotiating tactics and strategic vision, has served as the Indian ambassador to the US from 2013-2015.
A 1977-batch IFS officer, Jaishankar played a key role in resolving the crisis following the incursion in Ladakhs Depsang and the Doklam stand-off, handling the tough negotiations with Beijing.
Jaishankar, considered an expert on China and the US, was a key member of the Indian team which negotiated the landmark Indo-US nuclear deal. The deal, initiated in 2005, took several years to craft, and was signed by the UPA government headed by Manmohan Singh in 2007.
