The Federal Council does not want Switzerland to join the international task force set up to track down the money of Russian oligarchs.
Economy Minister Guy Parmelin told the Sunday press that membership is not in Switzerland's interest.
He said “In an increasingly polarised world, Switzerland has an interest, as a neutral country, in maintaining a certain restraint.”
The National Council is due to vote next week on a motion - put forward by the Green party - on whether or not to join the task force.
Switzerland is regularly criticised by its western allies over its somewhat hesitant implementation of sanctions against Russian oligarchs.
