BEIJING. February 20. KAZINFORM. Kazakhstan's foreign ministry on Monday denied there were any nuclear facilities within its borders, saying the nuclear facilities reported by some media to be located at nuclear test sites that were used by the former Soviet Union do not exist. Kazakhstan has volunteered to give up the world's fourth largest stockpile of nuclear weapons, shut down nuclear test sites inside its territory and become one of the initiators for the establishment of a non-nuclear region of Central Asia, said the statement. As a non-nuclear country, Kazakhstan will unconditionally honor its commitments under the nuclear Non-Proliferation Treaty (NPT) and the Comprehensive (nuclear) Test Ban Treaty (CTBT), it added. Kazakhstan will never develop, store or use nuclear weapons, said the statement, Kazinform quotes Xinhua.
