Due to the covid-19 situation, the Chinese government is not presently issuing L (tourist) visas, and nobody can say with absolute certainty what procedures they will put in place when they resume doing so.
However, you are correct that in the past, no financial information has been required in order to receive a Chinese tourist visa when applying from "rich countries"; as an example, I received a Chinese visa in 2016 without supplying any. However, it does appear that the requirements vary somewhat by country, and e.g. Ghanaian citizens were required to provide bank statements in order to apply for visas.
