Ukraine is forging ahead with embryonic plans for joint weapons production with some of its international allies, top officials said, while the U.S. announced it was halting some arms shipments promised to help Ukraine fight off Russia.

Axar.az, citing AP, reports that those plans come at what appears to be a key point in the all-out war launched by Moscow nearly 3 and a half years ago.

As Washington has distanced itself under U.S. President Donald Trump from Ukraine’s war efforts, a bigger onus has fallen on European countries to pressure Russia.

Ukraine President Volodymyr Zelensky said that officials are preparing with a sense of urgency for upcoming meetings with European Union countries and other partners to talk about cooperation in weapons manufacturing.

“One of the key topics will be weapons production – our joint investments, joint projects,” Zelensky said in his daily address on Tuesday evening.
