Germany has received what he called “signals” from European Union members that such training “could be interesting for them,” and that they might join the effort.

Erbil is the main city in the Kurdish-controlled region of northern Iraq.

Mr. Steinmeier’s announcement was the latest sign that Germany is ready to play a more robust role on the international stage, particularly in the Middle East and in addressing events in Ukraine. Germany’s relative proximity to Syria and Iraq, and its policies to date, have had a direct effect at home: Refugee facilities are overflowing, and there have been violent clashes between Kurds and the police in some German cities.

Azerbaijan shares a border with Iran, another focus of international diplomacy as the deadline nears for an agreement to limit Iran’s enrichment of uranium — and to prevent that country from developing a nuclear weapon — after almost a decade of negotiations.

In July, international negotiators extended the deadline on the Iran talks by four months, with discussions expected to come to a head in November, after the midterm elections for the United States Congress.

Mr. Steinmeier embarked on his trip to the Caucasus on Tuesday fresh from a dinner and talks with Secretary of State John Kerry. The two men indicated that Iran had taken up a good chunk of their time, with discussions about how much uranium Iran could continue to enrich, how much enriched uranium it might hold and how to prevent it from building a nuclear weapon.
