Gabriel told Germany's Funke media group: "If we can reach a smart agreement with Great Britain that outlines its relations with Europe after Brexit, then that could serve as a model for other countries," DW reports.
Berlin's top diplomat added that he could not see either Ukraine or Turkey joining the bloc anytime soon, and that the EU therefore "needs to consider alternative forms of closer cooperation."
