President Heinz Fischer said his six-month term will be one of reflection after voters in France and the Netherlands rejected an EU constitution, the BBC reports.
Fischer said a discussion over the constitution's terms will take place but no constitution will be put in place.
Romania, Bulgaria and Turkey are all applying for membership, with Turkey's bid remaining controversial.
A plan to ease trade restrictions between EU members is also expected to test Fischer's diplomatic skills. Britain is spearheading the trade change while others, including France, vehemently oppose it.
