The NICE model is based on the theory of ‘economic geography’ including ‘center and periphery'. This paper proposes a new kind of immediate neighbors policy in the Nepal, India, and China scenario that is an integrated economic geography approach to aid for trade which could help achieve mutual benefit in the implementation of UN sustainable development goals particularly ending poverty, hunger and ultimately providing for good health and well-being. The NICE and NICED models are demonstrated in and suggested for the trilateral diplomatic interaction of Nepal, India, and China.
