According to the Kathmandu Post, Swaraj will convey the "special political message" of Prime Minister Narendra Modi to Oli.
The External Affairs Minister will be accompanied by the new Foreign Secretary Vijay K. Gokhale and Sudhakar Dalela, Joint Secretary (North) of the EAM.
This will also be Swaraj's first visit to Nepal after the three-tier elections ended in December.
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)
