British Prime Minister Theresa May says a solution will require a willingness to make difficult decisions. She spoke after talks Thursday in Skopje with Macedonian Prime Minister Zoran Zaev.
Macedonia and Greece have been at odds over the small Balkan country's name for the past 27 years. Greece says it implies territorial claims on its own northern province with the same name, and on ancient Greek history. Macedonia denies that.
The dispute has prompted Athens to hinder Macedonia's NATO and EU membership bids.
May's was the first visit to Macedonia by a British prime minister in two decades.
