The Ukrainian president Volodymyr Zelensky today asked the leaders of the G7, the Group of Seven of the world’s most powerful economies, to approve a “Marshall Plan” to rebuild Ukraine after the damage caused by Russia’s invasion.

“We need a clear plan to restore Ukraine. Similar to what the Marshall Plan was for Europe after the war,” he told G7 leaders, according to a reading of his speech posted on the Ukrainian presidency’s website.

The Marshall Plan was a multibillion-dollar economic aid program that the United States provided to its European allies after World War II, and was credited with reviving their economies after the devastation caused by the war.

The World Bank has estimated that rebuilding Ukraine will cost nearly $500 billion.

Zelensky also said that the recent lifting of restrictions on the use of Western weapons on targets inside Russia gave Ukraine additional protection from airstrikes, particularly in the eastern Ukrainian city of Kharkiv.

“However, we are still seeking additional Patriot (air defense) systems and need more of the same strong steps that have been taken (to enhance) our long-range strike capabilities,” he said.
