PM Deuba is leading a 48-member delegation to the southern neighbour at the cordial invitation of Indian PM Narendra Modi. Former PM Oli also said that Nepal as the chair of SAARC should play a significant role to de-escalate geopolitical and other tensions existing in the region. He also opined that a bilateral energy policy unveiled by India was not in the interest of Nepal and would contribute nothing to the promotion of Nepal's energy sector.
