Addressing a two-day conference here, Chairman Joint Chiefs of Staff Committee General Zubair Mehmood Hayat said that Pakistan is not "oblivious to its defence".
He accused India of stoking "chaos and anarchy" in the region, Pakistan's state-run APP news agency reported.
He alleged that Indian's external intelligence agency RAW has established a special cell at a cost of USD 500 million to sabotage the CPEC. He also accused India of fanning terrorism in the restive province of Balochistan.
He said resolution of long standing Kashmir dispute is vital for durable peace in the region, the APP said.
The nearly USD 60 billion CPEC, a flagship project of Chinas prestigious One Belt One Road (OBOR), passes through Pakistan-occupied Kashmir (PoK).
The CPEC links China's restive Xinjiang region with Pakistan's Balochistan province.
