A guarantee of the right of ships of all flags to travel in the Pilawska Strait has become one of Poland's aims as a result of the lack of agreement on the part of the Russian government to open the strait for international shipping. In December 2004, however, a Polish project was presented for an agreement between the Republic of Poland and the government of the Russian Federation concerning shipping in the Vistula Lagoon and through the Pilawska Strait. The project proposes that the Pilawska Strait should be designated an international strait, in which shipping is only subject to Russian law and not to international law. The author of this essay does not agree with the official position of the Polish Ministry for Foreign Affairs in the matter of recognizing the Pilawska Strait as an international strait. He also does not agree with the international legal argument justifying Poland's claim to use the Pilawska Strait and the opening of the Strait to international shipping.
