Volodymyr Zelenskyy has said he is "deeply grateful" for Joe Biden's decision to prioritise air defence deliveries for Ukraine.
The Ukrainian president said his country was in critical need of the capabilities to protect its cities and civilians from Russian attacks.
"The partnership between Ukraine and the United States is strong and unwavering. Together, we are protecting life against terror and aggression," he added.
It comes after the US said a recent defence pact signed by Russia and North Korea was a "cause for concern".
