India has pressed Pakistan to enunciate its nuclear doctrine to ensure "transparency and predictability" of its atomic policy, local media reported Friday quoting official sources.

The demand was made at a meeting on nuclear confidence building measures (CBMs) earlier this week; the talks took place after nearly four years -- the last such engagement was in the Indian capital in 2007, the Financial Express reported.

It is learnt that officials from the Pakistan Army were part of the talks on December 27 in Islamabad, which was led by officials from the foreign ministries of the two countries, the newspaper said.

The sources said that in view of the concerns about the safety and security of Pakistan's nuclear weapons, there is a felt need for an official doctrine on their nuclear "command and control".

India, which has declared its nuclear doctrine, told Pakistan that if it demonstrates practical measures on "restraint and responsibility" towards its nuclear assets, it will be considered a "confidence-building measure" on the nuclear front, the newspaper said.
