Pakistan has said it won’t sign the nuclear Non-Proliferation Treaty (NPT) because it considers it discriminatory. “It is a discriminatory treaty. Pakistan has the right to defend itself, so Pakistan will not sign the NPT. Why should weIJ” the Dawn quoted Foreign Secretary Aizaz Ahmad Chaudhry as saying. The country has also reiterated its position on maintaining a credible nuclear deterrence in talks with the US, while seeking access to civil nuclear technologies to address its energy needs.
