The United States has pledged $2 billion (£1.5bn) to fund United Nations (UN) humanitarian programmes, but has warned the UN it must adapt or die.

The announcement was made in Geneva by Jeremy Lewin, President Trump's Under Secretary for Foreign Assistance, and the UN's emergency relief chief, Tom Fletcher.

It comes amid huge cuts in US funding for humanitarian operations, with further cuts expected from other donors including the UK and Germany.

Mr. Fletcher welcomed the new funds, stating they would save millions of lives. However, the $2 billion pledge is a fraction of the $17 billion (£12.6bn) the US contributed to UN humanitarian work in 2022.

Conditions attached to the funding specify that it will only focus on 17 countries, particularly Haiti, Syria, and Sudan, with Afghanistan and Yemen excluded due to concerns over fund diversion.

Restrictions on the funding also rule out projects related to climate change as they are deemed not life-saving or in the US interest.

Mr. Lewin, a Trump loyalist who has overseen drastic cuts to USAID, indicated that the UN must change its operational framework to receive further US support, emphasizing a need for targeted and efficient spending.

While the UN leadership appreciates the new funds, there is growing concern that the restrictive conditions undermine the principles of humanitarian aid. Excluding certain countries and crises could significantly impact those in need.

As global humanitarian crises become increasingly pronounced, many in the UN are acknowledging that even the reduced funding is better than a complete lack of resources.
