andyshrestha,

There is no purpose of having a wall when there is an open border policy. But when they have a visa system between India and Nepal, then some fences might be an option. And I think Nepal is benefitting more from India Nepal open border policy. India is 2nd fastest growing economy in the world whereas Nepal is top 25 poorest nation in the world. Indian can exists without Nepal but Nepal cannot exist without India. I know we are proud of our history but our present is scary.
It is embarrassing when you have to ask aid with a foreign government to repair 27km long road (ring road).
