US National Security Advisor Jake Sullivan says training of Ukrainian pilots to fly F-16 fighter jets will begin in the coming months.
Sullivan spoke to reporters on Saturday in the western Japanese city of Hiroshima where he is accompanying US President Joe Biden for the Group of Seven summit.
Sullivan said Biden informed the other G7 leaders of the US intention to train Ukrainian pilots.
The remarks came after White House National Security Council spokesperson John Kirby suggested on Friday that if Washington's European allies decide to provide the fighter jets, the US will respect their decisions.
Reporters asked Sullivan whether the Biden administration changed its stance, because the president had said in February that he had no plan to provide the fighters at the moment.
Sullivan replied that nothing has changed, adding that the US has provided Ukraine with weapons and training depending on the degree of emergency.
Asked about the possibility of escalating tensions with Russia, he said the capability Washington is going to provide Ukraine will not enable Kyiv to attack Russian territory.
