Koirala, who was on a three-day visit to India for the swearing-in ceremony of Modi as the 15th Prime Minister of India, held his first bilateral meeting with him in New Delhi yesterday.
India is interested in making investment in tourism, hydropower and agriculture sectors, Koirala told reporters at Tribhuvan International Airport on his arrival.
"India is positive to invest in Nepal's hydropower, tourism and agriculture sectors," he said.
Modi also assured him of every possible support in Nepal's development, Koirala said, adding that the former promised him to visit Nepal in response to his invitation.
During the 20-minute meeting, Modi expressed his desire to visit Nepal's famed Pashupatinath temple at a convenient time, media here reported.
Modi also directed authorities to expedite the pace of India-assisted projects in Nepal.
Minister of Physical Infrastructure and Transport Bimalendra Nidhi accompanying Koirala told The Himalayan Times over telephone from New Delhi that Modi showed concern about Nepal's constitution-drafting process.
"We still have to narrow down our differences on the model of forms of governance and federalism. If there is no consensus, we have agreed to get these issues settled by the Constituent Assembly (CA). I am confident that we will be able to draft a new constitution in time," Nidhi quoted Koirala as telling Modi.
Koirala said India had been kind to extend its support to Nepal's peace-building and constitution-drafting effort and he expected continued support on these fronts in the coming days.
Koirala told Modi he, too, was focusing on good governance and development.
According to Nidhi, Koirala lauded Modi for running an impressive election campaign that gave his Bharatiya Janata Party an absolute majority.
Koirala extended invitation to Modi for SAARC summit to be held in Kathmandu in November and requested him to visit even before the SAARC event.
