Many of these arguments strike me as particularly weak, none more so than slide 36, where he claims that China's urbanisation rate is being understated because they have a much higher population density threshold for what qualifies as a "city". He seems unaware that average farm size in China is absolutely tiny compared to America --- I've seen figures as low as 0.04 hectares (400 m2!) for Guangdong [1], which is how the province as a whole manages to achieve an Israeli-level population density of 486 persons/km2. For the whole of China, something like 0.2 hectares seems more reasonable.

But even then, if you take the definition he suggests for a "city" (400 persons/km2), every single farming village in China would qualify. That's why China has a much higher population density threshold for defining urban counties.
