Merkel, widely seen as Europe's most prominent proponent of a generous refugee policy, has firmly rejected a plan put forward by Seehofer to turn back at German borders any asylum seeker already registered in another European Union country.
The announcement by Kurz in Berlin after talks with German Interior Minister Horst Seehofer marks a shot across the bow at Chancellor Angela Merkel, who is trying to pull together a deal for European Union cooperation on placing asylum seekers.
German Chancellor Angela Merkel said Sunday (10 June) she was more open to French President Emmanuel Macron's plans to reform migration and defence policy in Europe than his hopes to bolster the euro.
The alleged rape and killing of a 14-year-old German girl by an Iraqi man, who was extradited from Iraq on Saturday, has re-ignited the debate on migrants and followed a scandal at a regional office which wrongly granted asylum applications.
The use of the phrase raised eyebrows on social media for its echoes of the World War II alliance of fascist powers, as well as the deep divisions in Europe left by the US-led invasion of Iraq in 2003 backed by a "coalition of the willing".
Seehofer is now trying to pull Germany's new government to the right and to adopt a harder stance on migration to win back territory from the populist Alternative for Germany (AfD) party which has gained their first seats in the legislature.

Describing her impression from Trump's behavior at the summit as "disillusionment", Merkel said that "we will not allow ourselves to be deceived again and again" and that Europe will not permit the American president to do "whatever he pleases".
However, a new anti-establishment Italian government is also vowing to turn away migrants - it has already forced one ship to divert to Spain - and it is unclear whether she will succeed.
Merkel said talks aimed at reaching agreement with Seehofer's party would continue.
Seehofer, the former premier of conservative Bavaria state, has always been one of the fiercest critics of Merkel's decision to open Germany's borders at the height of Europe's migration crisis in 2015.
"Italy is going further than other states: migrants will not be accepted in the ports any more".
The French president's office said in a statement: "International co-operation can not be dictated by fits of anger and throwaway remarks".
