The head of the Ukrainian-Polish parliamentary group from the Polish side, Jan Byra, and a number of other Polish parliamentarians called on Ukraine to "tighten" the Russian-Ukrainian border. The Polish parliamentarians addressed the following question to the head of the border control and registration department of the State Border Guard Service Department, Vitaliy Antoniuk, during a conference of the Ukrainian-Polish parliamentary group held in Lutsk: "When will Ukraine's eastern border be 'tightened' following the example of the western one?" Vitaliy Antoniuk was unable to give a clear answer to the question posed, stating that "for us (in Ukraine) there is no difference between borders" and that "the density of the Ukrainian-Russian border is no less than that of the western one." In turn, the Polish parliamentarians drew attention to the flow of illegal migrants, particularly from the countries of the Transcaucasus, who actually enter Ukraine unhindered for further movement to the West. Jan Byra also emphasized that if the Ukrainian-Russian border is tightened, it would be possible to discuss simplifying the crossing of the Polish border by Ukrainian citizens, in particular a visa-free regime. Among other problems, the Polish deputies drew attention to the problem of illegal Ukrainian labor migrants, the problems of churches and Polish burials in Ukraine, drug and human trafficking.
