UN Secretary-General António Guterres said on the 30th that the UN is facing a "sustainability-threatening" financial predicament and requires member states in arrears to take "immediate measures". 

UN Deputy Spokesperson Farhan Haq explained at a press conference on the 30th that this crisis originated from some countries' arrears in paying their dues and the UN's obligation to refund the withheld funds. 

The spokesperson pointed out that the UN had issued a warning as early as last November that the return of nearly 300 million US dollars in offset funds by the UN might "trigger a liquidity crisis", and current data shows that "such a situation is now imminent". 

After the news that Guterres personally wrote to several countries on the 29th to explain how the financial situation would affect the operation of the United Nations was leaked to the media, Hack said, "The above two factors have put us in an unsustainable situation." 

Although more than 150 countries fulfilled their obligations to pay their dues for 2025, by the end of last year, the United Nations still faced a record high of unpaid dues amounting to 1.56 billion US dollars. 

Huck warned that "if the overdue membership fees cannot be recovered or the refund of the deduction is not suspended, the United Nations may run out of all the funds needed to maintain its operation." 

The spokesperson stressed that the United Nations "has had to draw on reserve funds and resort to budgetary adjustments for many years to ensure its normal operation." 

He pointed out: "The current reserve funds are insufficient to ensure the necessary liquidity. This is a critical moment." He said that the proposals for reforming the budget management approach have been submitted to member states, and he believes that all countries "understand the severity of the situation and will take corresponding actions."
