The hasty admission of Ukraine to the European Union may cause the collapse of the association, said Portuguese Prime Minister António Costa .
"In order to be taken seriously and be consistent, the EU needs a new institutional and budgetary architecture, under the fear that this integration will not strengthen the EU, but its collapse, not support for Ukraine, but a trap for Ukraine."

Bloomberg columnist Andreas Kluth wrote that if Ukraine is granted full membership in the European Union, this will cause many new problems. Note that Denmark and the Netherlands opposed the entry of Ukraine into the EU. Before that, The New York Times analysts named four reasons why Ukraine will not become a member of the European Union or NATO in the near future.
