For instance, members of the ruling coalition stated that Seehofer is pursuing a strategy that contradicts the policy of the federal government.
"In the debate on the refugee issue, Seehofer clearly contrasted his position with the position of the Chancellor. I hope he will give up his trip," foreign policy expert and CDU member Roderich Kiesewetter said.
"Foreign policy is decided in Berlin and not in Munich," echoed the official representative of the SPD parliamentary group on foreign policy Niels Annen.
Seehofer has repeatedly made critical statements about Merkel's 'open doors' policy on refugees and even announced his intentions to file a lawsuit within Germany's Constitutional Court if Merkel failed to restore order on the German border.
Earlier, Seehofer was accused by his colleagues of playing into Putin's hands after he stressed the negative impact of anti-Russian sanctions on the German economy.
