Ukraine's external financing needs will be about $3 billion a month until 2023 at best, but could rise to $5 billion, IMF Managing Director Kristalina Georgieva said, Reuters reported.

She said IMF officials met with Ukrainian authorities in Vienna last week to discuss the country's financial needs and are working on a full-scale IMF lending program.

Georgieva strongly supported Ukraine's calls for a mechanism to coordinate financial needs and support. "We were part of the solution during the emergency phase. We are going to be a part of the solution during this recovery phase," the IMF leader said.

She praised Ukrainian leaders for continuing to manage the economy in "exceptionally difficult times." She said the international community has also pledged $35 billion to support the country in 2022, but it is critical to ensure that money not yet paid out is spent quickly.
