Ukrainian President Volodymyr Zelensky called on NATO allies not to 'wait months' and 'take strong decisions', amid concerns about the impact of a Trump presidency on military aid for his country, speaking at the 75th summit in Washington DC on Wednesday.

"It’s time to step out of the shadows, to make strong decisions work, to act and not to wait for November or any other month," he told them. "To this end, we must be strong and uncompromising."

"Don’t wait months! America can be great every day," he added, in an apparent nod to Donald Trump's own 'Make America Great Again' slogan. "Strong decisions are needed, and we are waiting for them, and we are counting on them."

He also added that 'Biden and Trump are very different, but they are supportive to democracy'.

"That is why I think Putin will hate both of them," he said.

Zelensky also used the event to say: "You want to kill Putin at this moment. And of course all of them, all of us. We want all of them, all of us, we want it very much. Really, he is not thinking."

Moscow had not commented at time of publication. It has repeatedly accused NATO of escalating the conflict with Ukraine and coming into 'direct conflict' with Russia.

NATO-sceptic Trump has repeatedly called on countries to 'pay their way' and has said that he had warned allies that he would 'encourage' Russia 'to do whatever the hell they want' to those that didn't. He has also promised to end the Ukraine conflict before his January inauguration, should he be elected president in November.

The 75th NATO Summit in DC began on Tuesday and continues until July 11, with leaders expected to focus on the Ukraine conflict among other issues.

According to media reports, Kiev is expected to be told it is 'too corrupt' to join the alliance at the current time, while there is also set to be opposition to outgoing Secretary General Jens Stoltenberg's plan for a 'multi-year' military funding package for Ukraine - widely seen as a way to negate the impact of a potential Trump presidency.
