There is speculation that after negotiations between the EU and Russia, the Snake Island has been exchanged for an unblocking of the transport blockade of Kaliningrad and transport to Kaliningrad should be restored next week.
But this is just speculation, I have no source.
EU is enemy of Russia. This is just an excuse for EU to blockade Russia. No way EU will lift blockade of Kaliningrad. Russia can forget about it. Don't forget, it was EU that funded Euro Maidan riot in 2013 / 2014 that ousted president Yanukovych.
