Something to remember here as this data is screwed slightly:

CNIPA VS USPTO

Link to data that talks to this: https://lnkd.in/gxuUpga6

Patent application pendency in China is generally shorter than in the United States; the Chinese Patent Office (CNIPA) announced a target of 16 months by 2022. Hence, the time from application to grant in China ranges from less than two years (if the applicant requests examination immediately) to more than four years (if the applicant takes the full three years to request examination).

According to CNIPA, the number of invention patent applications it received increased by more than 500 percent between 2009 and 2019, from 241,000 to 1.4 million (although, interestingly, there was a 9 percent decrease from 2018 to 2019). In comparison, the number of patent applications at the USPTO increased by only 35 percent (from 456,000 to 621,000) over the same time period. Hence, while in 2009 U.S. patent applications outnumbered Chinese applications by almost two-to-one, by 2019, the ratio had completely reversed.17 Most of the Chinese patenting increase can be attributed to applications filed by domestic applicants. Out of the 1.4 million CNIPA applications in 2019, domestic sources filed almost 90 percent (compared to 48 percent of USPTO applications).

Also great points Nitesh!
