In recent times, the people of the three Indochinese countries have fought brilliantly on
various fronts. In particular, the Battle of Highway 9 was a brilliant battle of annihilation,
effectively wiping out large numbers of enemy forces in an organized manner, achieving a
magnificent and inspiring victory. On behalf of the Communist Party of China, the Chinese
government, and the Chinese people, we extend our warmest congratulations to you and to
the fraternal peoples of the three Indochinese countries.
This victory is of great strategic significance. You have unleashed the unparalleled might of
people's war, achieved new heights, and gained new experience. You have dealt a heavy
blow to the U.S. invaders, defeated their aggressive plans, and made the Nixon [1]
administration's situation even more difficult and its life even more arduous. Your victory
fully demonstrates that the united strength of the three Indochinese peoples is formidable
and invincible.



The situation in Indochina is now unprecedentedly favourable. We firmly believe that the
heroic peoples of Laos, Cambodia, and Vietnam, united under the banner of the Supreme
People's Conference of Indochina, and continuing to persevere in people's war, will
overcome any difficulties and achieve complete victory in the war against the U.S. and for
national salvation.
