1979. They went in to ‘teach Viet Nam a lesson’ and promptly got their butts kicked. In all fairness Viet Nam had been fighting for 20 years. Not the case now but what’s a million Chinese?
RE: 1979. They went in to ‘teach Viet Nam a lesson’ and promptly got their butts kicked
It is dangerous to assume that the Chinese and Vietnamese military are the same today as they were nearly 2 generations ago.
Things have changed significantly since 1979.

At Lang Son, they are said to have destroyed Vietnam’s Gold Star division, a seasoned regular (i.e. non-draftee) unit that saw action during the Vietnam War. In addition, they killed 100,000 Vietnamese civilians, if the Vietnamese government’s claims are to be believed.

Then they shipped entire Soviet-built plants back to China at their leisure, without Vietnamese forces being able to interfere with their stately withdrawal, lest the incursion become a permanent occupation or even an outright annexation of the territory overrun.
* The Gold Star Division had run-ins with US forces in South Vietnam and had to be rebuilt from scratch, despite exaggerated Vietnamese claims of battlefield victories in the 60s, doubling or tripling the reported number of KIA inflicted on GIs in their area of operations as compared to the true numbers.
