“Update (1100ET): The Russian Foreign Ministry has responded to Lithuania's partial blockade of Kaliningrad, writing in a statement that they consider the "provocative measures" to be "openly hostile" and warning that the Kremlin may take action to "protect its national interests."”

This is Russia's first response.  Keep in mind that, Lithuania's President is an economist and the prime minister is also an economist.  So, you have two so-called experts running the country with no real-world experience in running anything other than Monetary Policy.
