Ukraine has expressed concern that Russia may be emboldened after the United States put a pause on a shipment of armament to Ukraine due to lessened stockpile concerns.

A decision by Washington to halt some shipments of critical weapons to Ukraine triggered warnings in Kyiv on Wednesday that the move would weaken its ability to defend against intensifying Russian air strikes and battlefield advances.

Ukraine is moving forward with plans for joint weapons production with allies while the U.S. halts some arms shipments.
