SEOUL - Cuban President Raul Castro sent a congratulatory message to North Korea's leader Kim Jong-un this week at the end of the 7th Congress of the country's Workers Party, state-run agency KCNA in Pyongyang reported Thursday.
"I am delighted to congratulate you on your election as president of Workers' Party of Korea during its 7th Congress," said Castro in his message sent Tuesday, a day after the congress concluded, according to the statement by KCNA.
Kim, who was already first secretary of the party since coming to power in 2011, was named "president" during the recent event, held between May 6-9 after 36 years, and amid intense international attention.
"I am convinced that the Workers' Party of Korea and the Communist Party of Cuba will strengthen the bonds of brotherhood and collaboration in the construction of socialism in our respective countries," Castro wrote in his message.
Castro's message to Kim shows both countries continue to maintain close ties despite the opening up of the Caribbean country in recent times even as North Korea remains at loggerheads with the international community over its nuclear and missile program.
North Korea has had a historical relationship with the Caribbean country, dating back to 1960 during the Cold War period.
Currently, the countries have cooperation agreements in several sectors, including education, oil, agriculture and trade, besides several diplomatic and cultural exchange programs.
