Swiss President Johann Schneider-Ammann took a hard line on EU immigration before meeting German Chancellor Angela Merkel on Wednesday, insisting Switzerland could not join a broader treaty Brussels wants, Reuters.
In an interview to broadcaster SRF, Swiss President also said Swiss plans to give local people hiring preference over the EU citizens and may not require any more EU negotiations for this.
Switzerland, which is not an EU member, must implement next year the result of a 2014 referendum in which voters demanded quotas on EU workers.
The EU also wants to replace around 120 sector-specific bilateral treaties with a broad new "framework agreement" that would make the Swiss automatically adopt many EU laws.
Such limits would violate bilateral treaties that give the Swiss enhanced access to the EU single market, their largest trading partner, in return for citizens' freedom of movement.
Schneider-Ammann, who holds the rotating presidency of his country's executive Swiss Federal Council this year, said his country will not be pressured into sacrificing sovereignty.
"Above all else, Mrs Merkel will hear from me that we are counting on the EU not to force upon us a connection between freedom of movement and a framework agreement," he said.
