"I welcome the agreement because I think that it is important for the Greek economy but also for the whole of Europe and NATO," NATO Secretary General Jens Stoltenberg said during a visit to Slovenia.
"The stability, economic prosperity (of Greece) is important for many reasons, but of course also important for the security of all our countries."
Stoltenberg described Greece as a "committed ally".
"It's an ally that has spent more than two per cent of GDP on defence for several years and I'm absolutely confident that Greece will continue to be a staunch and committed ally. Greece is going to invest in defence also in the future," he said.
