He also said that China was still following its previous policy of imperialism.
Participating in a discussion on "Imperialism of China and its impact on our internal security and our role" here last night, Singh said China was expanding its network in other neighbouring countries also.
"China's army was getting strong each day and there was a need to modernise the Indian Army to meet any eventuality," he said.
Singh said while the situation was stable in the north-eastern states, the central government should make efforts to resolve issues facing people there.
The former Army chief said vote-bank politics was a major threat to security of the country and pointed out that the number of Naxalite-hit districts in the country has risen from 52 to 270 due to government's policies.
