Swaraj is on a two-day official visit to Nepal in an effort to reach out to the country's political leadership ahead of the formation of a new government by a Communist alliance.
The timing of the visit comes at a time when India wants to improve its relations with Oli and his party, Communist Party of Nepal (Unified Marxist Leninist) (CPN-UML).
Relations between the two sides are often described as "patchy", where Oli criticised India's constant hindrance over Nepal's new constitution in 2015, which did not recognise the rights of the Madhesis.
On January 21, Prime Minister Narendra Modi telephoned Oli and congratulated him in advance on his win in the just-concluded Nepal elections and invited each other to visit their respective countries.(ANI)
