A message from the Communist Party of Vietnam emphasized that the Congress represents the Cuban Revolution’s historical continuity, the eternal spirit of the Sierra Maestra, the Bay of Pigs and Comandante en jefe Fidel Castro.

The Communist Party of China and the Communist Party of Vietnam, as well as the Democratic People's Republic of Korea’s Workers Party and the Lao People's Revolutionary Party, sent messages of congratulations and solidarity to the Communist Party of Cuba, on the occasion of the opening of the 8th Congress of the organization.

"The Communist Party of Cuba constitutes the leading nucleus of the revolution and the construction of socialism. In recent years it has led the Cuban people to achieve important results in economic development, in the improvement of living conditions and effectively confronting COVID-19. In this regard, we are very pleased," reads the text from the Communist Party of China’s Central Committee.

The message adds, "We are convinced that, under the firm leadership of the Communist Party of Cuba, the Congress will provide orientation as an important guide and inject energy into the development of socialism with Cuban characteristics. We reaffirm our commitment to work with the Cuban party to further promote the traditional friendship shared by China and Cuba, strengthen political confidence, deepen strategic communication and constantly enrich mutually beneficial, productive cooperation, to jointly achieve new accomplishments in the construction of socialism in both countries."

The missive from the highest leadership body of the Communist Party of Vietnam emphasized that the Congress represents the Cuban Revolution’s historical continuity, the eternal spirit of the Sierra Maestra, the Bay of Pigs, and Comandante en Jefe Fidel Castro.

"The special relationship between Vietnam and Cuba - in which the exchange between the two parties provides the political basis for improving bilateral relations and plays an important guiding role - has been constructed by the leaders of our revolutions, José Martí, Ho Chi Minh, Fidel Castro and several generations of Vietnamese and Cuban leaders. This special relationship continues to be cultivated and developed in all aspects, producing major achievements, demonstrating the firm, faithful revolutionary position of the parties, states, and peoples of both countries, contributing to revolutionary causes and socialist works in each nation. The unforgettable words of Comandante en Jefe Fidel Castro, "For Vietnam, we are ready to give even our own blood," will forever serve as the noble symbol of this sacred relationship," the message stated.

The Vietnamese text continues, "Despite innumerable difficulties and challenges, Cuba continues to relentlessly raise the victorious banner of revolutionary heroism, in the spirit of transparent internationalism, of indomitable struggle; with active participation in the struggles for national independence and social progress of the peoples of Latin America, the Caribbean, and the world."

Echoing these sentiments, the Korean Workers' Party expressed the certainty that this 8th Congress will make an important contribution to defending Cuba’s revolutionary conquests, guaranteeing the continuity and invariability of the socialist cause, achieving the country’s development, and promoting the people’s wellbeing.

"Relations between the parties and countries of Korea and Cuba were established in the common struggle against imperialism and for the successful advancement of the socialist cause; they were tested during complex, difficult international situations and today are being developed comprehensively following the needs of a new era," the Workers' Party's greeting notes, reaffirming the traditional ties of friendship, unity and cooperation shared by the two organizations.

The Lao People's Revolutionary Party also emphasized the importance of the Congress, which "will demonstrate the ongoing development of society and the strengthening of Cuban communists. We are confident that the resolutions adopted at the Congress will serve as guidelines and solid foundations for the welfare of the Cuban people," the congratulatory message states.
