Socialist International
The SPS wants to join the Socialist International. In May 2008, Ivica Dačić travelled to Athens to meet President of Socialist International George Papandreou. During this meeting, Papandreou said that Socialist International was ready to initiate the process for the SPS's membership. However, there is still some opposition within Socialist International to inviting the SPS, notably from the Social Democratic Party of Bosnia and Herzegovina. while Jelko Kacin claimed that Democratic Party president Boris Tadic lied about not blocking SPS from joining Socialist International.
