"Therefore, we say that we have Croatia and its accession talks in our sights. But we must also first see that, with the Lisbon treaty, we hopefully get a certain consolidation phase in terms of integration," she added in a speech on Europe to members of her conservative Christian Democrat party (CDU) in Berlin, Reuters reports.
Ms Merkel's comments come amid an already gloomy situation for EU aspirants.
Uncertainty over the EU's Lisbon treaty has diminished the willingness to see new countries let in not only in Germany, but also in other member states, notably France.
Additionally, the financial crisis has stolen the attention of leaders from EU enlargement concerns, and the western Balkans' own situation does not make matters easier.
