Congratulatory message from General Secretary and President of China Xi Jinping reads:

“I am very pleased to receive the news that you have been elected to the position of General Secretary of the Central Committee of the Communist Party of Vietnam. On behalf of the Central Committee of the Communist Party of China and on my own behalf, I would like to send you my warmest congratulations.

In recent years, the Communist Party of Vietnam has thoroughly implemented the spirit of the 13th National Congress Resolution, deeply promoted the Party building work, and achieved new achievements in promoting the construction of socialism and the cause of reform and opening up. We believe that, under the steadfast leadership of the Central Committee of the Communist Party of Vietnam, the entire Party and the entire Vietnamese people will successfully implement the goals and tasks set by the 13th National Congress of the Communist Party of Vietnam, firmly promote the preparation work for the 14th National Congress, and continuously strive towards the "two 100-year goals" of the founding of the Party and the founding of the country.

China and Vietnam are socialist neighbors with mountains and rivers connected by a strip of land. Last December, I paid a state visit to Vietnam, and both sides announced the establishment of a China-Vietnam Community of Shared Future, which has strategic significance, opening a new journey and a new chapter in the relationship between the two Parties and the two countries. I am willing to join General Secretary To Lam in leading the construction of an increasingly substantial and in-depth China-Vietnam Community of Shared Future, jointly promoting traditional friendship, consolidating political trust, deepening strategic exchanges, promoting substantive cooperation, bringing more happiness to the people of the two countries, and making positive contributions to the cause of peace and progress of mankind.

I wish you new achievements in your noble position."
