ANKARA, Turkey (AP) — Old foes Turkey and Greece will test a five-month-old friendship initiative Monday when Greek Prime Minister Kyriakos Mitsotakis visits Ankara.

The two NATO members, which share decades of mutual animosity, a tense border and disputed waters, agreed to sideline disputes last December. Instead, they’re focusing on trade and energy, repairing cultural ties and a long list of other items placed on the so-called positive agenda.

Here’s a look at what the two sides hope to achieve and the disputes that have plagued ties in the past:

FOCUSING ON A POSITIVE AGENDA

Mitsotakis is to meet with Turkish President Recep Tayyip Erdogan in Ankara on Monday as part of efforts to improve ties following the solidarity Athens showed Ankara after a devastating earthquake hit southern Turkey last year.
