Abstract
This paper aims at highlighting Romania's efforts to preserve the natural and historical
rights in connection with the Danube. Throughout its activity there are revealed interwar Romanian
diplomacy efforts for Romania to be a factor in the regulation of maritime and river navigation on the
Danube, the potential economic impact and solving the disputes that may arise in this area. The
research prior 1989, with significant results has been abandoned over the past two decades, which is a
risk to security and economic interests of Romania. The way Romanian delegation acted to the Paris
Conference of 1920-1921 can be a model for nowadays diplomacy. The problem was investigated, of
course, based on archival documents and available papers. We believe that the results can be
landmarks or reference points for further research on interests in the Danube basin.
