On July 31, Ukrainian President Volodymyr Zelensky said he had presented US President Donald Trump with Kiev's "main principles" for future arms deals.
In a video address, Zelensky said he and Trump had discussed large-scale deals on arms supplies, but did not provide any further information about the discussion.
Mr Zelensky did not even specify whether Mr Trump would agree to the proposed terms.
However, the Ukrainian leader still expressed hope that he could "implement all" principles with his American counterpart, while affirming that this would "strengthen both countries".
Last week, President Trump said that the US and the European Union (EU) had reached an agreement, according to which the bloc would pay " 100% of the cost of all military equipment" provided by the US.
Trump said the EU would receive orders and then distribute them to countries, with Ukraine receiving the majority of its weapons, including patriot air defense systems worth up to $1 billion.
"This will be a business deal for us," Trump said.
So far, at least eight NATO countries have expressed their willingness to contribute finances to the master plan, according to NATO Secretary General Mark Rutte.
For its part, Russia has repeatedly criticized the Western Provisions of weapons to Ukraine, warning that the move would not change the outcome of the conflict and lead to NATO's direct involvement in hostile actions.
