UNITED NATIONS, Jan 13 (Reuters) - U.N. Secretary-General Antonio Guterres appealed on Thursday for a suspension of rules preventing the use of money in Afghanistan to save lives and the economy and for a path to the conditional release of frozen Afghan foreign currency reserves. "International funding should be allowed to pay the salaries of public-sector workers, and to help Afghan institutions deliver healthcare, education and other vital services," Guterres also told reporters in New York. Some $9.5 billion in Afghan central bank reserves remain blocked outside the country, mainly in the United States, and international support given to the previous government has dried up since the Taliban seized power last August. "The function of Afghanistan"s Central Bank must be preserved and assisted, and a path identified for conditional release of Afghan foreign currency reserves," Guterres said. "We must do even more to rapidly inject liquidity into the economy and avoid a meltdown that would lead to poverty, hunger and destitution for millions," he said. U.N. aid chief Martin Griffiths is due to meet virtually with U.S. Secretary of State Antony Blinken on Friday. Guterres said they would discuss the creation of mechanisms to "allow for an effective injection of funds into the Afghan economy" that would also "create the conditions for the financial system in Afghanistan to be able to operate in the local currency." In December, donors to a frozen World Bank-administered Afghan Reconstruction Trust Fund agreed to transfer $280 million to the World Food Program (WFP) and U.N. children"s agency UNICEF to support nutrition and health in Afghanistan. "I hope the remaining resources -- more than $1.2 billion -- will become available to help Afghanistan"s people survive the winter," Guterres said. "For our part, the United Nations is taking steps to inject cash into the economy through creative authorized arrangements. But it is a drop in the bucket," he said. The United Nations on Tuesday appealed for $4.4 billion in humanitarian aid for Afghanistan in 2022, calling the funds an "essential stopgap" to ensure the country"s future. "The scale of that appeal reflects the scale of the despair. Babies being sold to feed their siblings. Freezing health facilities overflowing with malnourished children. People burning their possessions to keep warm," Guterres said. He warned that without more international effort "virtually every man, woman and child in Afghanistan could face acute poverty."
