 In modern times, the revolutions against the Ottoman Empire, the Balkan Wars, the World Wars and Yugoslav wars, and the Greek opposition to the NATO bombing of FR Yugoslavia, where Greece was the only NATO member to condemn the actions and openly expressed its disapproval (polls revealed that 94% of the Greek population were completely opposed to the bombing), and Greece's subjequent refusal to recognize the Kosovo Unilateral Declaration of Independence, backing the Serbian stance on this issue as one of the five European Union's member states that have done so, also have contributed to these relations.Greece is a strong supporter of the EU membership candidacy for Serbia, and in 2003 it has proposed the "Agenda 2014" for boosting the Euro-Atlantic integration of all the Western Balkan states into the Union.The two countries cooperate in security, tourism, culture and agriculture, with Greece being the third top investor from the EU to Serbia and the fifth overall (as of 2013).
