of the Cabinet of the Democratic People's Republic of Korea, Chairman of the Presidium of
the Supreme People's Assembly of the Democratic People's Republic of Korea Choi Yong-kun
Comrade:
On the occasion of the tenth anniversary of the signing of the Sino-DPRK Treaty of
Friendship, Cooperation and Mutual Assistance, on behalf of the Communist Party of China,
the Chinese government, and the Chinese people, we extend warm congratulations to the
Workers' Party of Korea, the DPRK government, and the fraternal Korean people.
The Sino-DPRK Treaty of Friendship, Cooperation and Mutual Assistance was signed on the
basis of the principles of Marxism-Leninism and proletarian internationalism. It fully
embodies the great friendship and fighting solidarity forged between our two peoples in the
long struggle against imperialist aggression. This treaty plays an extremely important role in
comprehensively developing the friendly and cooperative relations between our two
countries, opposing the aggression of U.S. imperialism and Japanese militarism, and
safeguarding peace in Asia and the world.
Over the past decade, the international situation has developed increasingly in favor of the
peoples of all countries and unfavourably of U.S. imperialism and reactionaries in various
countries. Unwilling to accept defeat, U.S. imperialism is using ever more insidious and
cunning tactics to continue pursuing its policies of aggression and war. Japanese militarism,
revived under the aegis of U.S. imperialism, is ambitious and accelerating its military
expansion, having become a dangerous force of aggression in Asia. The aggressive plots and
activities of the U.S. and Japanese reactionaries are being strongly condemned and
resolutely opposed by the Chinese people, the Korean people, and the people of all Asian
countries.
The great friendship and fighting unity between the Chinese and Korean peoples, forged
with blood, are time-tested and unbreakable. If the U.S. and Japanese reactionaries dare to
impose a war of aggression on the Chinese and Korean peoples, the Chinese people will, as
always, resolutely unite with the Korean people and fight shoulder to shoulder to completely
defeat the invaders.
Long live the great friendship and fighting unity between the Chinese and Korean peoples!
