Maria Kolesnikova, the Tsepkalo and Tikhanovskaya ally who remains in Belarus, has criticized the EU’s planned sanctions against Minsk as premature, warning that the penalties may make a dialogue with the authorities difficult if not impossible https://www.dw.com/ru/marija-kolesnikova-schitaet-sankcii-es-v-adres-minska-prezhdevremennymi/a-54578661
The pushback would seem to suggest that the opposition — or a segment of it — is still counting on a negotiated transfer of power, such as through round table talks
Alternatively, it’s possible the opposition fears that the EU response is playing into Lukashenko’s hands and risking a Russian intervention of some sort by (geo)politicizing the unrest
This, despite the discipline with which EU member-states have focused their criticism of Minsk on human rights abuses and election manipulation and avoided talk of geopolitics or a civilizational choice
Indeed, Poland has in recent days admitted that the political crisis in Belarus cannot be solved without Moscow
Kolesnikova also expresses opposition to economic sanctions, though as far as I know the EU is contemplating targeted sanctions only
