Ukraine President Volodymyr Zelensky on Thursday said that his country needed as much as $7 billion per month to keep its economy afloat and compensate for “economic losses” caused by Russia’s invasion.

Speaking via virtual means to a World Bank forum on a financial lifeline for Ukraine, the 44-year-old said, “[The] Russian military are aimed at destroying all objects in Ukraine that can serve as an economic base for life. That includes railroad stations, food warehouses, oil, refineries.”

Zelensky also spoke about the Russian blockade of Ukraine’s Black Sea ports, which he said has not only affected exports and global food security, but also adversely affected Ukraine’s economy.

The figure of $7 billion is an increase from Kyiv’s previous estimate of $5 billion a month, Zelensky said, adding that considerably higher amounts would be required in future to help rebuild the war-torn country and restore its economy.

The Ukrainian President went on to say that Russia was “using aggressive methods in world markets while fighting this war,” and told World Bank officials that Ukraine would require “hundreds of billions of dollars” for rebuilding.

World Bank President David Malpass, meanwhile, said that a “narrow” estimate of physical damage to Ukraine’s buildings and infrastructure stood at a whopping $60 billion since the war began on February 24, adding that “a recovery plan for Ukraine, similar to [the] Marshall Plan for Europe after the Second World War” would be needed in the aftermath of the war.

The virtual meet was also attended by US Treasury Secretary Janet Yellen, who had earlier announced the doubling of the US’ direct non-military aid to $1 billion.

“The needs of Ukraine are urgent, and we plan to deploy this direct aid to Ukraine as soon as possible to be used on most urgent needs. We know this is only the beginning of what Ukraine will need to rebuild. And I’m committed to working with Congress and with our international allies and partners to build on this support in the medium and long term,” Yellen had said at a news conference earlier.
