According to the Korean Central News Agency (KCNA), Kim signed the condolence book at the Cuban Embassy. When at the embassy, the North Korean leader was accompanied by the country's senior officials and the senior members of the governing Workers’ Party of Korea (WPK).
"Although the outstanding leader died, his name will always be kept alive in our memory," Kim wrote, as quoted by the agency.
Cuba established diplomatic relations with North Korea in 1960, shortly after Castro came to power, and maintains an embassy in Havana. Military and commercial ties between the two communist states have increased since Raul Castro came to power in 2008. In July 2013, the countries’ relationship was scrutinized following the interception of a ship carrying Cuban weapons to North Korea in Panama.
The funeral of Castro has been set for December 4 and is expected to be held at the cemetery of Santa Ifigenia in the country's second largest city of Santiago de Cuba.
