British Foreign Minister Boris Johnson says his country will continue to be involved in European issues even after it leaves the European Union.

Speaking Friday after meeting his Austrian counterpart Sebastian Kurz in Vienna, Johnson said the two talked about the migrant crisis in Europe and emphasized "we in the UK are very, very keen to continue to tackle that sort of issue together, whatever our relationship with the European Union."

Britain decided in a summer referendum to leave the EU, but hasn't yet activated the clause to begin its exit.

Johnson, who supported the so-called Brexit, said he was "very clear" with Kurz that "we're not leaving Europe, we are leaving the European Union, we do want a strong European Union, but we also want a strong United Kingdom."
