The Bulgarian embassy last week marked the country's Liberation Day amid deepening ties with Korea that reached a "comprehensive and future-oriented partnership" last year, The Korea Herald said.
The holiday celebrates the national independence of 1878 from the Ottoman Empire, which ruled Bulgaria for over 500 years.
The new alliance, announced in a joint presidential declaration during the state visit of Bulgarian President Rosen Plevneliev to Seoul last May, covers comprehensive areas including political dialogue, trade and investment, science and technology, education, culture and people-to-people exchanges.
"Last year was remarkable in our bilateral relations, as we marked the 25th anniversary of establishing diplomatic relations during the official visit of our president to Korea from May 13-15," said Bulgarian Ambassador Petar Andonov in a speech at Grand Hyatt Seoul on Thursday.
"Bulgaria and Korea are committed to advancing fundamental values of democracy, the rule of law and human rights, and finding durable solutions in sustainable development, nuclear nonproliferation and other international issues."
During the presidential visit, Andonov said, several memorandums of understanding were signed for cooperation in defense, science and technology, education, culture and sports.
They include a memorandum between the Southern Europe Sofia Tech Park and Samsung Electronics for an innovation ecosystem called "Room of the Future," which opened inside the Sofia Tech Park in December, as well as another between the Bulgarian Association of Computer Software Companies and the Gyeonggi Center for Creative Economy and Innovation.
Other important memorandums were signed between the Executive Agency of Small and Medium-sized Enterprises of Bulgaria and the Korean Federation of Small and Medium Businesses, between the Association of Bulgarian Exporters and the Korean Importers Association and between the Confederation of Employers and Industrialists of Bulgaria and the Federation of Korean Industries.
