Addressing a seminar on 'Indian Army-Emerging Roles and Tasks', Singh said that the rise of terror infrastructure across the western border and Beijing's rising military force were a worry for the country.
"We have two irritants. One, Pakistan where there is a problem of governance and where the internal situation is not very good. Secondly we have a rising China, both economically and militarily advanced. Although we have a very stable border, yet we have a border dispute," he added.
Singh said that a conventional war with China or Pakistan was "highly uncertain" but some minor short-term fight may occur.
"We should have a great amount of conventional capability to function in a conventional conflagration and yet be prepared to function in a nuclear backdrop," he said.
