35 foreign parties congratulated the CPV on holding its 10th Congress. Among these were ruling parties of the remaining socialist states, the Communist Party of Cuba, the Communist Party of China (CPC) and the Lao People's Revolutionary Party. Hu Jintao, the former CPC General Secretary of the Central Committee, personally congratulated Nguyen Van Son, the Chairman of the CPV Commission for External Relations, on the CPV's holding of the 10th National Congress. Not all the parties which congratulated the CPV were communists, for example the Cambodian People's Party, the Workers' Party of Korea, the Social Democratic Party of Germany, the Uri Party and the Bulgarian Socialist Party.
