"Such a decision has been taken. We are holding talks on supplying the helicopters," Chemezov said, adding that the negotiations were about Russian Mi-35 Hind attack helicopters, the ITAR-TASS news agency reported.
Russia has long been the largest supplier of arms to India, which is the world's top arms buyer.
But Moscow's move to supply Islamabad came as New Delhi is seeking to modernise its armed forces' ageing hardware and has recently chosen to buy arms from Israel, France, Britain and the United States.
"This is an important, key change in Russian policy in the region," he told AFP.
"The sale of arms to Pakistan will abruptly worsen our relations with India, the main buyer of our arms... This risks dismantling our cooperation with India," Felgenhauer said.
