Whenever the topic of Chinese infrastructure comes up I am reminded of a 2016 Wired documentary about Shenzhen. It was positive portrayal of hacker culture in Shenzhen. But one thing really stood out to me. They had demarcation line separating the city and “urban village”. It looked like lots of poor people lived in the urban village. The guide mentioned that the urban village will be torn down completely in 3 months to expand the city and people had to move. It sounded like gentrification. The host was impressed by the efficiency.

But it made me question how many countries can actually be that “efficiency” because matters of uprooting large swath of population will take years not months and run into significant legal challenges as well.

To be clear use of eminent domain and gentrification happens even in US but I doubt it can be as “efficient” as a technocratic government. It’s not a knock on Chinese government, just something I always wonder.

Tearing down a slum is not gentrification.

Gentrification is when existing communities that used to have decent if basic living situations get gradually priced out of an area as richer people and their expensive amenities move in. Gradually, as house prices go up and food gets more expensive, people sell and move. It's a slow, mostly voluntary thing, or at least, driven by market forces rather than official mandates.

Tearing down a slum is a much more disruptive thing that instantly displaces a entire community. Although it's unclear what happened to that community in this case and I can't find anything clear about it online (lots of clearly biased articles for one side or the other though).
