The president of the Fourth International Conference of Small Island Developing States (SIDS), Gaston Alphonso Browne, accused wealthy nations of empty climate pledges on May 27, referring to a lack of financial help to developing countries, along with the inadequacy of carbon emission reduction efforts. The summit, entited "Charting the Course Toward Resilient Prosperity," was hosted by Antigua & Barbuda, where Browne serves as prime minister. Browne blasted developed nations for failing to meet their "obligation to compensation" to the SIDS nations. This refers to the annual $100 billion that was agreed to under the 15th Conference of Parties (COP15) of the United Nations Framework Convention on Climate Change (UNFCCC) in 2009 and reiterated in the 2015 Paris Agreement.

The Kenya High Court on May 17 ordered that a lawsuit seeking to prevent the deployment of police troops to Haiti be served on top government officials.

The plaintiffs argued that the government's agreement with Haiti to deploy the troops is in contempt of a January court order that deemed the deployment unconstitutional. The plaintiffs emphasized the urgency of the matter, noting that the deployment is scheduled to begin this month.

France accused Azerbaijan on May 17 of interfering in the conflict in New Caledonia, and spreading anti-French propaganda on social media to enflame the unrest in the French overseas territory. The charge was based on a report published by the French state investigative agency Viginum, alleging that Azerbaijan has disseminated "manifestly inaccurate or misleading content—photo or video montages—blaming France for its handling of the situation in New Caledonia in the context of the riots." The report came one day after French Interior Minister Gerald Darmanin accused Azerbaijan of making an agreement with the New Caledonia independence leadership, implying that this was retaliation for French support of Armenia in the conflict between the two Caucasus nations. Darmanin further added that France will not cede to the violence, and that it maintains sovereignty over New Caledonia.
