Bavaria's state premier Horst Seehofer wants to “suspend” the Schengen agreement, which guarantees freedom of movement and abolished border controls between European countries which have signed up to it, at the state's border with Austria.
The Christian Social Union (CSU) decided on the most important parts of its programme on Friday at a meeting led by party leader Seehofer.
Bavaria has become a target for refugees entering Europe through Italy and then heading towards Austria. In July, police in Munich reported a "huge increase" in the number of people arriving illegally at Munich's main train station with 600 arrivals in June and July.
Bavarian government figures show almost 17,000 people applied for asylum last year.
“Lampedusa can't become a suburb of Kiefersfelden [the Bavarian-Austrian border town],” CSU secretary-general Andreas Scheuer reportedly said at Friday's meeting, referring to the Italian island where many refugees have landed after fleeing their homeland in recent years.
“Italy has clearly violated the Schengen agreement,” Seehofer told Bild on Monday. “If that isn't fixed, Germany must really consider putting a stop to it with border controls.”
But the party's suggestions met with immediate resistance from their allies, Merkel's Christian Democratic Union (CDU).
“To tighten borders would be a sign of powerlessness and a confession that the authorities in Germany don't work fast enough,” said Peter Hauk, leader of the CDU group in the Baden-Württemberg state parliament.
Germany was recently praised by the UN High Commissioner for Refugees who called Germany's refugee policy "an example for other European countries to follow".
A CSU spokesman contacted by The Local said that renewed border controls were not yet part of party policy, as they first have to be agreed at a party board meeting on Monday.
Other demands of the CSU include an increase in staffing levels at the Federal Migration and Refugees Office, repurposing disused barracks to house refugees, and an increase in funding of €100m for refugees and development aid, to be put under the control of CSU Development Aid Minister Gerd Müller.
Many towns in Bavaria are complaining that they are now overburdened with asylum seekers and refugees. Opposition politicians and refugee organisations have accused Seehofer of failing to react in time.
"The current situation is the payback for the short-sighted asylum policy of recent years," said Ben Rau of the Bavarian Refugee Council. "The Bavarian government must admit its failure and use the opportunity to finally introduce a long-term, humane accommodation policy."
Under the Schengen agreement and EU border regulations, refugees are supposed to remain in the country in which they first arrive so that the burden can be shared among member states.
But Italy has been accused of turning a blind eye to the refugees passing through the country so that they don't become a burden on its social security system.
Interior Minister Thomas de Maizière recently promised more support to Italy so that the country can deal with the large numbers of refugees arriving on its shores as EU rules require.
