Sources familiar with the matter said that the US and NATO are working to develop a new approach to provide weapons to Ukraine. In particular, NATO member states will still be the ones to pay for the purchase or transfer of weapons from Washington.
Under this approach, Ukraine will prioritize the necessary weapons in batches, each worth about $500 million. NATO allies will then negotiate on their own to decide who will sponsor or pay for the items on that list.
An unnamed European official said that NATO allies hope to provide Ukraine with tens of billions of dollars in weapons through the new mechanism. However, the specific time frame for the supply of these weapons is still unclear.
"It's a starting point and an ambitious goal that we are aiming for. We are currently on that trajectory. We support this ambition, the European official said.

Another NATO official said the initiative was "a voluntary effort coordinated by NATO in which all allies are encouraged to participate". The new plan would include a NATO holding account where allies could send money to buy weapons for Ukraine, which would be approved by NATO's top military commander.
However, NATO headquarters in Brussels ( Belgian) declined to comment on the above information, while the White House, the Pentagon and the Ukrainian Embassy in Washington did not respond to the request for comment.
This renewed transatlantic cooperation comes as US President Donald Trump has become increasingly impatient and has expressed dissatisfaction with Russia's continued intensification of attacks on Ukraine.
Trump, who initially spoke more conciliatively with Russia in trying to end the more than three-year conflict in Ukraine, threatened to impose tariffs and other measures if Moscow did not show progress in ending the conflict before August 8.
