Washington: The White House announced Thursday that it will provide Ukraine with USD 335 million more in security assistance.
The announcement came after a meeting between US Vice President Joe Biden and Ukrainian President Petro Poroshenko in Washington.
The aid is vital to a country that has faced an acute economic and security crisis since Russia annexed Crimea in 2014 and fomented a separatist revolt in Ukraine's east.
While Washington has looked to support Ukraine's pro-western government, it has also been concerned by rampant corruption in Kiev.
Thursday's announcement comes after Ukraine's parliament sacked the country's chief prosecutor over his alleged attempts to stall high-profile corruption investigations.
According to the White House, Biden told Poroshenko more money could be on the way.
"The vice president welcomed the efforts of President Poroshenko to form a stable, reform-oriented government, and stressed that this step, as well as the enactment of needed reforms, are critical to unlocking international economic assistance, including the third USD 1 billion US loan guarantee."
In May of last year the United States signed its second USD 1 billion loan guarantee deal for Ukraine, aimed at helping it surmount the Russia-backed insurgency and rebuild its tattered economy.
