Summary: The sanctions ban could strain the Bilateral III negotiations. The EU expects coherence in sanctions policy from associated states. The temporal parallelism of both proposals intensifies the tension.
The Bilateral III package was signed on 2 March 2026 [1] and transmitted to Parliament on 13 March 2026 [2]. The popular vote is expected to take place in 2027/2028 -- shortly after the vote on the Neutrality Initiative.
The EU expects states with close market access to demonstrate coherence in foreign policy, particularly regarding sanctions. A constitutional sanctions ban could be perceived as a signal of distancing [3].
