"We are disturbed by media reports that India might be considering to conduct additional (nuclear) tests," said Foreign Office spokesman Abdul Basit to a weekly news briefing.
Pakistan does not "discuss the contours of our deterrence in public" but is committed to maintaining a "credible deterrence at the minimum levels," he said.
Basit added Pakistan would oppose any arms race in South Asia
"We have proposed a regional restraint regime, including a regional nuclear test ban treaty. The proposal is still on the table. We hope a unilateral moratorium on testing in the region will continue to be observed," Basit said.
