United Nations Secretary General Kofi Annan on Thursday urged India to sign the Comprehensive Nuclear Test Ban Treaty that is against nuclear testing.
He also asked India to support another treaty that will put a cap on the production of fissile material needed for making atomic weapons.
"I hope India will soon sign and ratify the CTBT, and also give active support to the negotiations on a fissile material cut-off treaty," Annan said.
India, which came out of the nuclear closet in 1998 conducting five tests, has resisted signing the CTBT describing it as discriminatory.
