The United States on Monday announced nearly $6 billion in additional military and fiscal aid for Ukraine, as President Joe Biden uses the final weeks of his term to increase aid to Kiev before President-elect Donald Trump takes office.

Biden announced $2.5 billion in additional security assistance for Ukraine.

Treasury Secretary Janet Yellen said the United States made an additional $3.4 billion in budget aid to Ukraine, giving the war-torn country critical resources amid intensifying Russian attacks on Ukrainian civilians and infrastructure.

“Under my guidance, the United States will continue to work tirelessly to strengthen Ukraine’s position in this war for the remainder of my termBiden said in a statement.

Biden’s announcement includes $1.25 billion in military aid drawn from US reserves and a $1.22 billion Ukrainian Security Assistance Initiative (USAI) package, the last USAI package during Biden’s tenure.

According to USAI, the military equipment is procured by the defense industry or partners, rather than drawn from US stockpiles, meaning it can take months or years to reach the battlefield.

Yellen said in a statement that the immediate fiscal assistance, provided in coordination with the U.S. Agency for International Development and the State Department, marked the final disbursement under the Ukraine Security Supplemental Appropriations Act of 2024.

The U.S. Congress approved blanket aid 175 billion dollars for Ukraine since Russia’s invasion of Ukraine almost three years ago. Recently the Russians have been using North Korean troops to strengthen their fighting position.

North Korean forces are suffering massive casualties on the front lines of Russia’s war against Ukraine, with 1,000 of its troops killed or wounded in the last week alone in Russia’s Kursk region, White House spokesman John Kirby said Friday.

Biden said the new aid would give Ukraine “an immediate influx of capabilities that it continues to use with great effect on the battlefield and long-term supplies of air defenses, artillery and other critical weapons systems.”

Nearly three years after the war, Washington has committed billions of dollars in aid to Ukraine, but it is uncertain whether aid will continue at that pace under Trump, who succeeds Biden on January 20.

Trump has said he wants to bring the war to a quick end.

During the presidential campaign, Trump questioned the level of US involvement in the conflict, suggesting that European allies should bear more of the financial burden.

Some of his fellow Republicans – who will control both the House of Representatives and the Senate starting next month – have also been reluctant to send more aid to Kiev.

A US official said the $3.4 billion in budget funding brings total US budget aid to Ukraine to more than 30 billion dollars since the invasion of Russia in February 2022. Most of these funds are used to keep the government of Ukraine running by paying salaries to teachers and other state workers.

Washington has separately provided about $61.4 billion in security assistance to Kiev since the start of the war, according to the Pentagon.

Biden said the Defense Department is in the process of delivering hundreds of thousands of artillery rounds, thousands of rockets and hundreds of armored vehicles “which will strengthen Ukraine’s hand as it heads into winter.”

Yellen said continued financial aid to Ukraine was vital to allow it to maintain government services and continue to defend its sovereignty, warning of moves to cut funding.

“Ukraine’s success is in America’s core national interest,” she said, pledging to continue to pressure Moscow with sanctions and help Ukraine achieve a just peace.

“We must not give up in this effort».
