during the Gulf War, particularly during its service as president of the UN Security Council. Romania has been active in peacekeeping operations in UNAVEM in Angola, IFOR/SFOR in Bosnia, Albania, in Afghanistan and sent 860 troops to Iraq after the invasion led by the United States. Romania has developed strong relations with Hungary, with the latter playing a key role in supporting Romania's bid to join the EU. Romania's ethnic Hungarian party also participated in all the government coalitions between 1996 and 2008 and from 2009. In 1996, Romania signed and ratified a basic bilateral treaty with Hungary that settled outstanding disagreements, laying the foundation for closer, more cooperative relations. Bulgarian relations with Romania feature regular official visits by the two presidents. In the first half of the 20th century, Romania and Bulgaria had a serious conflict over the Dobruja region. This dispute, while now largely forgotten, escalated into all out war in 1913. The territorial dispute between the two countries ended with the Treaty of Craiova.
