Read the full account

On 8 October 1950 Mao Zedong issued the order constituting the Chinese People’s Volunteers to enter Korea, after days of Politburo argument and cables with Stalin. Peng Dehuai was appointed commander. Chinese units crossed the Yalu in mid-October. This is a war-entry decision, not the 25 June North Korean attack and not the later armistice.

Context

Kim Il-sung had started the war with Soviet support. US and UN forces had reached the Yalu approaches. Some Chinese leaders feared US invasion; others feared a ruinous war. Stalin’s conditions on air cover shifted. Zhou handled diplomacy.

What the sources establish

The Wilson Center Digital Archive publishes Mao–Stalin–Kim traffic and related notes. Britannica independently dates Chinese intervention to October 1950. No Factrail original killed-in-action census is offered.

Established: Mao ordered PVA entry on 8 October 1950 after a Politburo process. Not established: that he planned the 25 June invasion, or a unique death total.

Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.

If a number is not in the two records named above, it is not supplied here.

Confidence is stated on the impact path, not hidden in adjectives. Mixed effects of Mao orders the People’s Volunteer Army into the Korean War are separate paths.

That reading is an impact-path choice, not a property stored on the Fact itself.
