Would China intervene to help North Korea if war broke out?

This is a tough call. On one hand,historically both North Korea and China have had a close relationship with economic ties and both being communist governments. The last time there was a war on the Korean peninsula, China leaped in to save North Korea. On the other hand, with the death of Mao's hardline communism and Deng Xiaoping taking over, China has now embraced technocracy, free trade with the west and foreign policy pragmatism. China today has serious issues with North Korea being basically a rogue hermit kingdom, and has communicated it's displeasure to North Korea. China has also condemned North Korean rocket tests and its nuclear weapons program.

China just like in the 1950's would not want the US allied South Korea and US forces stationed right on their border though. What do you think? I would vote No, as long as the US and SK, stayed 10-25km from the Yalu river frontier.

No, they won't give up on their largest trading parting to support an almost worthless buffer state

Yea North Korea is a total failed state, and close to zero economic value to the PRC. Weirdly enough, up until the mid 1970's North Korea had a higher GDP than South Korea. Now South Korea has 30-40 times the GDP of North Korea. Right now China also has strong trade links with South Korea and why would they want to ruin that?

I wonder what the poll would have looked like for the original Korean War, or Russia intervening in Austria-Hungary's invasion of Serbia.

I think without hindsight, people would have thought China was bluffing and would stay out of Korea. Hard to say with Russia after they lost to Japan in 1905. Russia was still chest thumping with it's Panslavism though.
