"I don't believe we can completely stop illegal migration on the German-Austrian or German-Polish borders," Angela Merkel said, speaking at the Sudwest Presse forum.
At this event, he read excerpts from his book and answered journalists' questions.
Merkel emphasized that unilateral restrictions by European countries risk losing the Schengen system and ending the right to free movement within Europe. Therefore, he recommended paying more attention to the protection of the EU's external borders.
