VILNIUS, July 12. /TASS/. NATO believes its priority is to supply Kiev with advanced weapons systems and a huge amount of ammunition and spare parts for them, NATO Secretary General Jens Stoltenberg said on Wednesday.

"I think we realized many months ago that this is a war of attrition, meaning a battle of logistics. It’s important that we deliver different advanced weapons systems, but as important as delivering new systems is that we are able to maintain and sustain all the systems that are already there. An enormous amount of ammunition, spare parts maintenance and repair capacity," he said at a news conference following a NATO summit.

Stoltenberg also said Ukraine’s future position at the negotiating table will hinge on the outcome of its counteroffensive.

"I think it’s wrong to speculate exactly how this will be done in the future after the war ends. The most important thing now is to ensure that the war ends in a just and lasting way. That’s the reason why the most urgent, the most important task is a continued flow of military support," he said.

The NATO official earlier said the bloc had decided to spare Ukraine the requirement of executing a Membership Action Plan and pledged to invite the country to the alliance when all the conditions were met.
