Dear Comrades, On the occasion of the 21st National Congress of the Communist Party of India (Marxist), on behalf of the Vietnamese communists and people, we would like to extend to the Congress and to all members of the Communist Party of India (Marxist) our warmest congratulations. We are delighted to see that the Communist Party of India (Marxist) has been persistently pursuing Marxism-Leninism and the struggle for a socialist alternative in India. We strongly believe that the 21st National Congress will continue to lead the Communist Party of India (Marxist) to greater achievements, for an India of peace, independence, democracy and social progress. May the solidarity, friendship and cooperation between our two parties and people of the two countries Vietnam-India be further strengthened and developed. We wish the 21st National Congress of the Communist Party of India (Marxist) a great success. With fraternal greetings, Central Committee Communist Party of Vietnam
