BUCHAREST, May 28 (Xinhua) -- The volatile security situation in the Black Sea Extended Region, marked by the existence of conflict potential, would persist on the short and medium term, Romanian President Klaus Iohannis underscored in a message on Monday.

Iohannis sent the message on the occasion of launching the 2018 edition of the "Security in the Black Sea Region. Common Challenges, Sustainable future" program.

The message was read by Mihai Somordolea, state adviser with the National Security Department and secretary of the Supreme Council for National Defence, according to official Agerpres news agency.

According to the message, the regional geostrategic landscape is also influenced by a series of current threats and challenges, such as international terrorism, hybrid war, frozen conflicts, migration crisis, cyber and communications attacks, and the transnational nature of those threats to security requires the cooperation of the riparian states in the Black Sea area.

"No country has the power or resources to solve on its own the complex issues the contemporary world is confronted with," said Iohannis, voicing his support for the efforts to promote regional partnerships and initiatives devoted to identifying and efficiently approaching the security challenges the Black Sea region is confronted with.

The Black Sea represents a significant connecting bridge between Europe, the Middle East and Central Asia, with the possibility to capitalise on the Danube as transit corridor to Central Europe, the Baltic Sea region and towards the Mediterranean Sea, Iohannis added.
