"Greece is a pillar of stability in the Eastern Mediterranean," said Prime Minister Kyriakos Mitsotakis, attending the NATO Summit in Brussels.
US President Joe Biden, for the first time since his election, will take part in the work of the Summit today.
"Greece is coming to invest increased resources in its armaments capabilities so that it is even more consistent in its allied obligations," said Mitsotakis.
Before the start of the Summit, Mitsotakis met at the NATO building with the Prime Minister of Albania, Edi Rama, and immediately afterwards with his British counterpart, Boris Johnson.
At 17:05 Greek time, immediately after the completion of the Summit, which will last only three hours, Mitsotakis will have a private four-on-four meeting with Turkish President Tayyip Erdoğan.
