I think the issue was Google Search's summarization algorithm parsed the wrong sentence in a non-verified website (I did the same search you did and recreated your issue).
Also, the same thing holds for China as well. BKK =/= Thailand and Shanghai/Beijing/Tianjin =/= China as well. Not to mitigate the massive amount of development that China has seen the past 20 years, but Thailand's subregional development (measured via HDI) is very even - the poorest region (Isan) has a HDI of around 0.781 and the richest (BKK the prefecture, not the city) is around 0.839 in 2021. Compared to China outside of Tier 1 cities it's a significant difference (and on a separate note Ik Chinese policymakers have been looking into Thailand's anti-poverty policies to replicate them in Shaanxi)
