The European Union unveiled a massive $55 billion, multi-year proposal to rebuild Ukraine this week as the war with Russia still rages on. 

On the eve of the Ukraine Recovery Conference in London Wednesday, the European Commission announced a proposal for a dedicated financing instrument to foresee up to €50 billion ($55 billion) from 2024 to 2027, "to help Ukraine resist the aggression and rebuild a modern, prosperous country." 

The European Commission, the executive arm of the EU, said the new "Ukraine Facility" will support "Ukraine's efforts to sustain macro-financial stability, promote recovery as well as modernize the country whilst implementing key reforms on its EU accession track," as well as, "support the transition towards a green, digital and inclusive economy that is progressively aligned with EU rules and standards." 

The facility also opens the possibility to use contributions from other donors as well as revenue generated by frozen and immobilized Russian assets as a contribution to Ukraine's recovery and reconstruction, according to the commission, which noted, "work is ongoing on the possible use of Russian assets for Ukraine's recovery and reconstruction."

A joint assessment between the Ukrainian government, World Bank Group, the European Commission and the United Nations estimated in March that the cost of reconstruction and recovery in Ukraine has grown to $411 billion (€383 billion) within the first year since the Russian invasion began. 

The multibillion-euro project revealed by the commission Tuesday serves as the first major economic grouping to describe a detailed, multi-year funding plan toward reconstructing Ukraine. 

Meanwhile, Ukraine’s allies pledged several billion dollars in non-military aid on Wednesday to rebuild its war-ravaged infrastructure, fight corruption and help pave the membership in the European Union. 

Stressing the vast scale of the task, diplomats and political leaders at the Ukraine Recovery Conference in London urged private-sector companies to invest and revive an economy battered by almost a year and a half of war. Delegates from more than 60 countries attended the conference, which is both a fundraising forum and a message to Russia that Ukraine’s allies are in it for the long haul.

Secretary of State Antony Blinken said the U.S. would give more than $1.3 billion in new aid, including more than $500 million to restore and improve Ukraine's battered energy grid. 

Before the conference, Blinken said post-war Ukraine will need "the strongest possible economy, the strongest possibly democracy" in order to attract the investment it will urgently need. He also highlighted anti-corruption efforts, saying some of the U.S. money will go toward upgrading ports and border infrastructure and digitizing customs procedures to cut graft.

In addition to European Commission President Ursula von der Leyen’s 50 billion euros ($55 billion) in support through 2027, Britain pledged 240 million pounds ($305 million) in aid and 3 billion pounds ($3.8 billion) in World Bank loan guarantees for Ukraine.

Ukraine President Volodymyr Zelenskyy, who addressed delegates by video, said his country needed action. 

"We must move from vision to agreements and from agreements to real projects," he said. "We are only waiting for the courage of the alliance leaders to recognize this reality, politically."

Many say Ukraine needs the equivalent of the Marshall Plan that helped rebuild Europe after World War II. Its infrastructure had been decimated by Russian attacks even before the collapse of the Kakhovka dam this month after an explosion flooded some 25,000 acres of land and displaced thousands of people.

The conference Wednesday aims to harness private-sector investment. British Prime Minister Rishi Sunak said BT, Virgin, Philips and Hyundai Engineering are among more than 400 companies from 38 countries that have committed to invest in Ukraine.

Politico reported that BlackRock and JPMorgan Chase are working with the Ukrainian government on a new development fund that would engage seed capital for rebuilding and reconstruction projects.

"Reconstruction is already happening. It’s part of our resistance," Oleksandra Azarkhina, Ukraine's deputy minister for communities, territories and infrastructure development told Politico. "Ukraine needs help — not just on the battlefield, but in terms of private and public investment."
