Nursultan Nazarbayev, the president of the Republic of Kazakhstan signed the historical decree on closure of Semipalatinsk test site (STS), one of the biggest test sites in the world, where 459 nuclear explosions had been conducted. Under the President's initiative Kazakhstan chose its future without nuclear weapons and today, years later, it is obvious that it was the only right choice. The genuine components of our security are not nuclear weapons stockpiles, but the peaceful foreign policy, internal stability, sustainable economic and political development. In this context the signing and ratification of the Treaty on Nuclear Weapons Free Zone in Central Asia is a logical extension of our President's initiative in the field of regional and international security strengthening.

The initiative on establishment of the Nuclear Weapons Free Zone in Central Asia was developed under the UN aegis and this point has made the initiative successful. The number of resolutions was passed by UN GA to support the idea of Central Asian zone creation.

Free of nuclear weapons zones designed to eliminate the possibility of any action with nuclear weapons in certain regions of the world and contribute to the development of nuclear energy peaceful uses. Such zones are developing under the Treaty on the Non-Proliferation of Nuclear Weapons. They are one of the mechanisms of its implementation as it is one of the most effective means of achieving the main objective - global nuclear safety.

For the first time a zone free of nuclear weapons was established in Latin America and the Caribbean in 1967. Treaty includes all states of the region. After this agreement three more had been signed establishing such zones: South Pacific (The Treaty of Rarotonga, 1985), Southeast Asia (Bangkok Treaty, 1995), Africa (Pelindaba Treaty, 1996) and includes more than 100 countries. Central Asian zone was the fifth in the world. Mongolia declared its Nuclear-Weapons-Free Status too.

Adopted a special law prohibits production, storage, transportation and testing of nuclear weapons on its territory.

As it is said in Semipalatinsk Treaty States Parties have pledged to ban the production, acquisition and deployment of nuclear weapons and their components or other nuclear explosive devices in the region. It should be noted that the Treaty does not prohibit the development of national peaceful nuclear programs.

Protocol on the negative assurances is an integral part of the Treaty. Under the Protocol the nuclear weapon states pledge not to use or threaten to use nuclear weapons to any country participating contract.
