BERLIN - German Chancellor Angela Merkel stressed the importance of a European solution for the refugee issue on Tuesday.

"When we think too small, when we only think about ourselves, then this will be a major threat to Europe," she said on the day to mark German industry.

She called on the approximately 1,200 representatives in politics and business in Germany to promote a common response overseas to the challenges of the refugee movement.

"Those who today think in Europe that they were not affected, will be affected in some way tomorrow, even if the unity of Europe would be put into question," Merkel added.

The Chancellor again pleaded for a more equitable distribution of refugees in Europe. It was necessary to a European approach, she said.

"We must insist that the burden within the European Union (EU) will be distributed fairly, otherwise the system will not work," said Merkel.

Merkel also stressed that the abolition of internal borders in Europe and the relocation of border guards at the EU's external borders would only be achievable with the help of Europe's neighbors.

She insisted that an agreement between the EU and Turkey would be quickly closed.
