The US government has announced significant cuts in its United Nations budget obligations for 2018-2019 in what will be interpreted as a further ratcheting up of pressure from the Trump administration looking to bend decision-making at the international body to its will.

In a statement released over the holiday, the US Mission to the United Nations said next year’s budget would be slashed by over $285 million and unspecified reductions would also be made to the UN’s management and support functions.

“We will no longer let the generosity of the American people be taken advantage of,” US ambassador to the UN Nikki Haley said in a statement. Haley added that the “inefficiency and overspending” of the organisation is well-known.

Under the UN charter, the US is responsible for 22 per cent of the the body’s annual operating budget, or around $1.2bn in 2017-2018, and 28.5 per cent of the cost of peacekeeping operations, estimated at $6.8bn over the same period.

In her statement, Haley said she was pleased with the results of budget negotiations, and the US Mission would continue to “look at ways to increase the UN’s efficiency while protecting our interests”.
