However, Western allies are still negotiating language to signal their long-term commitment to Ukraine.

Ukrainian President Volodymyr Zelenskyy has been pushing for a concrete pledge that Ukraine will be welcomed as a member after the war.

NATO is working on a package of practical and political support for Ukraine, including helping it adopt Western military standards and determining the appropriate language to use regarding its bid.

The alliance is divided on the issue, but discussions are ongoing.

A meeting of NATO foreign ministers in Oslo brought the allies closer together on the question of what to offer Ukraine.
