Efforts to strengthen non-proliferation since the 1960s have been a central focus of the international community, driven by the recognition of the devastating consequences of nuclear weapons use and the desire to prevent their spread. The cornerstone of these efforts is the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), signed in 1968 and entered into force in 1970. The NPT has played a pivotal role in shaping the global non-proliferation regime, and numerous measures have been undertaken to enhance its effectiveness.

1. The NPT: The NPT remains the fundamental instrument for non-proliferation efforts. It is a multilateral treaty that comprises three key pillars: (a) preventing the spread of nuclear weapons and nuclear weapon technology (non-proliferation); (b) promoting disarmament; and (c) ensuring the peaceful use of nuclear energy. Since its inception, periodic Review Conferences have been held to assess its implementation and make necessary adjustments. These conferences have contributed to strengthening the treaty and fostering a sense of shared responsibility among signatories.

2. Safeguards and Verification: The International Atomic Energy Agency (IAEA) plays a critical role in enforcing non-proliferation. The IAEA's safeguards agreements provide for inspections and verification of the peaceful use of nuclear technology, ensuring that states are not diverting it for military purposes. Over the years, the IAEA's authority and capabilities have expanded to enhance its ability to monitor nuclear facilities effectively.

3. Bilateral and Regional Agreements: A significant number of bilateral and regional
