US President Joe Biden has offered Ukraine 60 million dollars in new security assistance to help deal with aggression from Russia.
Biden and Ukrainian President Volodymyr Zelenskyy held their first face-to-face meeting at the White House on Wednesday.
Biden said at the outset of the meeting, "The United States remains firmly committed to Ukraine's sovereignty and territorial integrity in the face of Russian aggression."
Zelenskyy thanked Biden, saying the two countries are ''truly strategic partners."
The leaders discussed security and defense as well as energy and climate issues.
The US said the security assistance package is to enable Ukraine to more effectively defend itself against Russian aggression.
In Ukraine, some critics say US moves should be closely watched as Washington has been holding talks with Russia to improve ties. The US has also withdrawn from Afghanistan, indicating that it wants to avoid military involvement on issues that are not in their national interest.
