German Chancellor Olaf Scholz called on Saturday for the enlargement of the European Union.
He said in his speech at the Congress of European Social Democrats in Berlin that doing so would make the bloc better able to face global challenges.
Since taking office, Mr. Scholz has made the expansion of the European Union with the Balkan countries and others a priority of his foreign policy.
This issue has become more urgent since the beginning of Russian aggression in Ukraine, which became a candidate for EU membership at the beginning of the summer.
"An EU of 27, 30, 36 states, with more than 500 million free and equal citizens, could have even greater weight in the world," Mr. Scholz told the congress.
"I am committed to the enlargement of the EU. Enlargement of the EU to the east would be beneficial for all of us," he said.
Chancellor Scholz also called for reforms to the European Union, which he said would help make enlargement possible and allow for military autonomy for the 27-nation bloc.
Mr. Scholz spoke about the need to gradually remove the principle of unanimity for decisions in foreign policy, but also in other areas such as tax policy.
"If our aspiration is a geopolitical Europe, then the decisions of the majority are a strengthening and not a loss of sovereignty," he said.
Currently, many EU decisions can only be taken if all countries vote unanimously.
Mr Scholz also supports more military autonomy for the EU. He called for coordination in the supply of arms and equipment and the creation of an EU rapid reaction force by 2025.
"In Europe, we need better interoperability of our defense efforts," he said. "In the future, Europe will need a coordinated increase in capabilities. We must move European defense forward with conviction and together."
