The government today informed the Rajya Sabha that the United States has not requested India to sign the CTBT in recent bilateral discussions.
In a written reply, Minister of External Affairs S M Krishna said CTBT does not affect the October 10, 2008 agreement which enables civil nuclear cooperation between India and Pakistan.
"India has declared a voluntary, unilateral moratorium on nuclear explosive testing," he said.
Giving a list of the countries which have signed the CTBT, he said India, Pakistan and DPR Korea have not signed it while 181 states have signed the treaty.
