Chinese entry into the Korean War
19 Oct 1950 — At night, the first units of the Chinese People’s Volunteers cross the Yalu at Andong (Dandong), unseen by American reconnaissance. The name “volunteers” allows Beijing to fight the United States without declaring war. Over the next three years, close to three million Chinese serve in Korea.

The moment in context
The Korean War began with a northern invasion, but by autumn 1950 the forces approaching China were American-led. The UN landing at Incheon in September reversed the course of the fighting.

Premier and foreign minister Zhou Enlai warned through the Indian ambassador that China would act; Washington dismissed the warning as bluff. Mao judged the danger of remaining outside the war greater than the danger of entering it.
