Ghana ratifies treaty on prohibition of nuclear weapon

Ghana has officially ratified the Treaty on the Prohibition of Nuclear Weapons (TPNW), reaffirming its longstanding commitment to global peace and security.

The Minister for Foreign Affairs, Samuel Okudzeto Ablakwa, announced the development during the commemoration of the International Day for the Total Elimination of Nuclear Weapons in the US.

The ratification builds on Ghana’s historic leadership in global disarmament, dating back to 1962 when the country, under Osagyefo Dr. Kwame Nkrumah, hosted the World Without a Bomb Conference in Accra. Since then, Ghana has played a key role in advancing Africa’s nuclear-free status and supporting global efforts to eliminate weapons of mass destruction.

Officials say the move reinforces Ghana’s support for international legal frameworks such as the Nuclear Non-Proliferation Treaty (NPT) and highlights the country’s belief in effective multilateralism as the foundation for building trust and ensuring collective security.

Ghana’s final ratification of the TPNW—signed in 2017 and approved by Parliament in July 2025—places the country among a growing number of states working towards a nuclear-free world. It also underscores Ghana’s foreign policy priorities and its role as a consistent advocate for peace both in Africa and globally.
