I would say developing the transportation system would be the most important. The rural areas won’t be so isolated. Communication will be faster. The business opportunities will increase. Folks who could only sell in a 10 mile radius would be able to go longer and farther distances and sell their goods and also buy good for cheaper b/c the competition will increase.

Then concentrate on exports. Maximize exports minimized imports.

Above all we would need people willing to invest MONEY and time in Nepal
