Antony said the efforts should be instead on improving the country's infrastructure.
"We are aware of some nations augmenting infrastructure and modernising their military capabilities. Instead of unduly worrying over this we must improve our infrastructure at a steady pace. At the moment, we are doing that," Antony said.
He was addressing the silver jubilee function of the Army Aviation Corps.
Observing that the challenges to be faced by the armed forces in future would range from terrorism and internal disturbances to asymmetric and conventional warfare, Antony said, "The non-conventional threat of terrorism poses a threat to the global peace and all nations have to unite to tackle these evil designs."
