Bildt suggests that the Bosnian format of a peacekeeping mission is most applicable in Donbas: "To be sure, not every issue in Eastern Slavonia was sorted out then or in the years since; but there is no longer a conflict, and Croatia and Serbia now enjoy constructive bilateral relations. This could be a model for the separatist-controlled areas of Donbas if the political will is there to make such an arrangement work."

"Such a mission could then ensure the real implementation of the political provisions of the Minsk II agreement. Genuinely free and fair local elections, with the participation of all displaced people and refugees," said Bildt, according to Ukraine Today.

Bildt is also skeptic about Moscow’s readiness to restore normal dialogue with the West.
