The Lithuanians are fully within their rights to deny foreign powers the privilege of transiting Lithuanian territory.
Kaliningrad is not landlocked - there is thus no question about Lithuania being obligated to permit (sanctioned) Russian cargo to transit sovereign Lithuanian territory.
Regards,
In general, I agree with you. No obligation to transfer on your property. With that said, I’m sure there is an agreement in place for the transit, and the reason they provided to stop it is EU sanctions. I don’t think that reason is technically correct in this case, as it is a transfer from Russia to Russia. Maybe I’m wrong, although I’ve read recently they are allowing the transit through there again. Now if they go ahead and declare war, totally get transit stops then.
