France officially supports the universalisation of the NPT. In 2006, it stated officially that France, alongside the European Union, called all non-parties to join the NPT as non-nuclear weapon states. No information is available on specific outreach activities towards these states.
No new development has occurred since 2022 regarding the implementation of this action. The support for the universalisation has been reiterated in the National Report submitted to the 2026 Review Conference.

The UK continued to press strongly for NPT universalisation and stated that it raised this with non-NPT states parties at every opportunity.
The G7 Non-Proliferation Directors Group statement of April 2021 confirmed the G7's priority to promote universalisation of the NPT and called on all states to accede to the Treaty as non-nuclear-weapon states.
The United Kingdom continued to call on all states that are not party to the NPT to sign and ratify the Treaty as non-nuclear-weapon states at the earliest opportunity. The UK states that it attaches great importance to the universalisation of the NPT.
The G7 Non-Proliferation Directors Group statement of August 2025 called on all states that have not yet done so to accede to the NPT, and committed to working with all states to achieve a successful 2026 Review Conference.
The UK does not say what it has done to work towards this beyond making this type of statement.

US efforts were instrumental in bringing the Non-Proliferation Treaty to near-universal adherence, and President Clinton made the negotiation of an indefinite extension to the NPT a central priority of his administration. These efforts continued in successive administrations; in 2003, Assistant Secretary of State for Nonproliferation John S. Wolf stated that ‘US support for the goal of universal NPT adherence remains undiminished. We do not support any change to the NPT that would accord a different status to states currently outside the Treaty.’
In 2005, however, the Bush administration reached an agreement with India on a deal that would lift the moratorium on US nuclear trade with India and provide US assistance to India's civilian nuclear energy program. Critics of the agreement suggested that this agreement undermined the United States’ support for the universality of the NPT, given that it normalized India’s status as a nuclear weapon state outside the bounds of the NPT.
During the current Review Cycle, the United States has continued to stress the importance of the universalization of the NPT. In its 2025 report assessing compliance with arms control and non-proliferation agreements, the United States stated that it ‘supports universal adoption of the AP by States Parties to the NPT.’
During the second Trump administration, however, the United States has undertaken actions that critics suggest could undermine its previous support for core tenets of NPT. For example, the Trump administration has proposed several avenues for U.S.-Saudi nuclear energy cooperation, which could potentially include the forgoing of Saudi safeguards and nonproliferation requirements as a prerequisite to a deal. While the conclusion of such a deal would not require either country to withdraw from the NPT, it could undermine the spirit of the treaty depending on its exact parameters.
