"Nothing to do with that kind of initiative," said Guterres, when asked if he was creating a U.N. version of Trump's Department of Government Efficiency, which is spearheaded by Musk and has made sweeping cuts to the U.S. federal workforce.

"We are talking about completely different processes, methodologies and objectives. This is a continuation and an intensification of work that we have always been doing," he told reporters when announcing the creation of a UN80 taskforce.

Two U.N. officials, speaking on condition of anonymity, acknowledged that Trump's return to office in January had added urgency and ambition to the efficiency effort.

Trump said in February that the U.N. has "great potential and ... we'll continue to go along with it, but they got to get their act together." The U.N. pushed back at the time, saying Guterres has worked tirelessly to implement reforms.

"My objective is to move as soon as possible in areas where I have the authority – and to urge member states to consider the many decisions that rest with them," Guterres said.

"This goes far beyond the technical. Budgets at the United Nations are not just numbers on a balance sheet – they are a matter of life and death for millions around the world. We must ensure value for money while advancing shared values," he said.

The move comes as the United Nations, founded in October 1945, faces a liquidity crisis for at least the seventh year in a row. Not all 193 U.N. member states pay their mandatory regular dues in full or on time, Guterres said.

UNCERTAINTY

The regular budget for the United Nations in 2025 is $3.7 billion, which includes political, humanitarian, disarmament, economic, social affairs and communications work. Contributions to most U.N. agencies, funds and programs - such as the World Food Programme and children's group UNICEF - are voluntary.

The top two contributors to the regular budget, according to assessments agreed by the U.N. General Assembly, are the United States and China. Washington pays the maximum 22%, while Beijing's contribution rose 5% this year to 20%.

However, China is now paying its dues at the end of the year - six months later than it once did. The United States is in arrears, owing $1.5 billion. Washington last made a payment of $275 million in November, under Trump's predecessor, Joe Biden.

One of the U.N. officials said there was "a lot of uncertainty" with the budget this year. China had assured the U.N. it would pay in full this year, but it was unclear when, while Washington was not yet in a position to indicate to the U.N. how much it would contribute, the official said.

"We have decided, between January and August, to be very prudent financially," the official said.

As of March 7, 75 member states - just over one third - had paid their regular budget assessments in full. Amid the cash crunch, the United Nations has reduced planned spending by up to 20% and imposed a hiring freeze.

When asked about possible job cuts as a result of the UN80 efficiency effort, the official said: "At this point I can't say. What I will say is that everything is on the table and nothing is off the table."
