In a letter to the United Nations (UN) staff, Secretary-General Antonio Guterres urging member states to pay their mandatory contributions on time and in full warns of risk of running out of cash.

The UN Chief has stated that the contributions are necessary to ensure that the world body can continue to deliver on its key mandates.

Guterres added that UN's cash flow has never been this low so early in the calendar year highlighting the risk the current situation poses to the delivery of mandates and to the reputation of the organisation.

As of July 26, 112 member states, including India, have paid their regular budget dues in full. A total of 81 nations are yet to pay their regular budget dues. These include Afghanistan, Bangladesh, Brazil, Egypt, Israel, Maldives, Pakistan, Saudi Arabia, Seychelles, Sudan, Syria, the United States and Zimbabwe among others.

The United States is the biggest contributor to the United Nations, paying 22 per cent of the 5.4 billion dollar core budget and 28.5 per cent of the 7.9 billion dollar peacekeeping budget.
