Cuba’s Decree-Law on Chemical Weapons (1999) states:
NOTING: Cuba has shown its clear intention to support all actions towards the non-proliferation of weapons of mass destruction, as well as the consequential destruction of those that already exist in any part of the world, in light of the catastrophic consequences that their use would have on humanity and for the future of the planet.

NOTING: The Republic of Cuba as a State Party to the Chemical Weapons Convention must comply with its obligations through the full incorporation of the said international treaty [into its domestic legislation] which requires the establishment of provisions that regulate its fulfillment.
THEREFORE: … The Council of State issues the following

During the 1991 Session of the Conference on Disarmament, Cuba stated:
For Cuba, a country which does not possess chemical weapons, the conclusion of a non-discriminatory convention which prohibits the development, stockpiling, acquisition, transfer and use of these weapons and makes the necessary provision for the destruction of existing stockpiles, production facilities and launching systems, is not only of crucial importance but is an essential guarantee in its perception of security.

In 1991, during a debate in the First Committee of the UN General Assembly, Cuba stated that it neither possessed nor produced chemical weapons.

In 2009, in a statement during a general debate of the First Committee of the UN General Assembly, the representative of Cuba stated:
Cuba reiterates its unwavering commitment to the [1993] Chemical Weapons Convention and the [1972] Biological Weapons Convention and supports all actions taken to make them universal. The total destruction of existing chemical arsenals is the most important task of the Organisation for the Prohibition of Chemical Weapons (OPCW).

In 2009, in a statement before the First Committee of the UN General Assembly on other weapons of mass destruction, the representative of Cuba stated:
The Cuban delegation fully aligns itself with the statement made on this subject by the representative of Indonesia on behalf of the Non Aligned Movement.
The existence of weapons of mass destruction continues to constitute a grave threat to international peace and security. Cuba reiterates its call for general and complete disarmament under strict and effective international control, including the prohibition of all weapons of mass destruction.
Efforts made by States in the context of disarmament processes must be aimed at the complete and total elimination of such weapons and at the prevention of the emergence of new kinds of weapons of mass destruction. Cuba reaffirms the importance of compliance by all States with their obligations in connection with arms control, disarmament and prevention of the proliferation of weapons of mass destruction in all its aspects.
In the context of the [1993] Convention on Chemical Weapons, Cuba continues to play an active role, urging the implementation of that instrument because it contemplates … disarmament, including verification … . Cuba also supports all steps aimed at achieving the universalization of the Convention.
The total destruction of existing chemical weapons, including abandoned chemical weapons, within the agreed deadlines is and will continue to be the most important goal of the Organisation for the Prohibition of Chemical Weapons (OPCW). It is crucial that the major chemical weapons countries comply strictly with destruction deadlines, which have already been extended. Failure to do so would jeopardize the credibility and integrity of the Chemical Weapons Convention.
Cuba does not possess, nor has it any intention of possessing, weapons of mass destruction of any kind. As a State Party to the international legal instruments that prohibit weapons of mass destruction, Cuba renews its firm commitment to the total and effective implementation of all their provisions.
Cuba remains fully committed to the objective of the total elimination of weapons of mass destruction.

In 2010, in a statement before the First Committee of the UN General Assembly, the representative of Cuba stated:
Cuba emphasizes its commitment with the strict application of the [1993] Chemical Weapons Convention … . The total destruction of the chemical stockpiles is the most important task of the Organisation for the Prohibition of Chemical Weapons. This Organization has, in addition, an important role in the promotion of the economic and technological progress of the State Parties, particularly of the less developed ones.

In 2011, in a response to UN General Assembly Resolution 63/51 on the observance of environmental norms in the drafting and implementation of agreements on disarmament and arms control, the representative of Cuba stated:
The Republic of Cuba has accumulated vast experience in the adoption and application of laws and policies that allow it to observe environmental norms … including their application in various International Instruments in the field of disarmament and arms control to which it is a State Party: [including] the [1993] Chemical Weapons Convention (CWC), … among others.
Cuba affirms that the only truly effective solution to avoid the dire consequences of the use of weapons of mass destruction continues to be the total elimination of this type of weapons, and considers the universalisation of international treaties that prohibit them of great importance. The existence and continuous refinement of weapons of mass destruction constitute the most serious threat to international peace and security, the fragile environmental balance of our planet and the sustainable development of all peoples without distinction.
The Chemical Weapons Convention continues to be the only international agreement that includes the destruction of these weapons and installations that produce them in a verifiable way, as well as measures for the protection of people and the environment. Of great importance are the “principles and methods relating to the destruction of chemical weapons” which possessor States must bear in mind when they destroy them. However, some of possessor States have continued to extend the period for their destruction, and today it is known that they cannot destroy their chemical weapons before the date established in the Convention, in the year 2012. This situation is the cause of grave concern to the Organisation for the Prohibition of Chemical Weapons (OPCW).

In 2011, in a statement before the First Committee of the UN General Assembly, the representative of Cuba stated:
Cuba emphasizes its commitment to the strict implementation of the Chemical Weapons Convention …
The total destruction of existing chemical arsenals is the most important task of the Organisation for the Prohibition of Chemical Weapons (OPCW). With less than one year until the final extended deadline for the destruction of all chemical weapons the OPCW is facing growing challenges which need to be addressed promptly by its member States in order to achieve the necessary consensus to enable the integrity and credibility of this important Convention and Organization to be preserved.
