The United States, under President Donald Trump, initiated a significant shift in its foreign policy by formally announcing its withdrawal from 66 international organizations, including 31 entities affiliated with the United Nations and 35 non-UN bodies. This decision, formalized through a presidential memorandum signed on January 7, 2026, directs US executive departments and agencies to cease participation and funding to these organizations. The comprehensive list of withdrawals targets various sectors, notably climate governance institutions like the UN Framework Convention on Climate Change (UNFCCC) and the Intergovernmental Panel on Climate Change (IPCC). It also includes social policy organizations such as UN Women and the UN Population Fund (UNFPA), and significantly, the India-France-led International Solar Alliance. In response, UN Secretary-General António Guterres expressed regret over the US decision but emphatically stated that the UN's 'responsibility to deliver' for those who depend on it would not waver. The UN underscored that assessed contributions to its regular and peacekeeping budgets are considered a legal obligation for all member states under the UN Charter. UN officials indicated they would continue implementing their mandates with determination, despite learning of the withdrawal through news reports rather than formal communication. This move is characterized by the Trump administration as an effort to protect American sovereignty, eliminate wasteful spending, and reject 'globalist agendas' perceived to conflict with US national interests. However, it has drawn widespread criticism globally, with concerns raised about the potential negative impacts on multilateral cooperation, climate action, humanitarian assistance, and the evolving international power balance. For India, the withdrawal from bodies like the International Solar Alliance carries direct implications for its strategic interests in global climate and energy initiatives.
