At the time (1826), America's per capita GDP was $2,460, which is 68% of the UK's per capita GDP of $3,600. Today, China's per capita GDP is $16,000, or 29% of of the US's per capita GDP of $55,000.
Japan is about $39,000, Germany is $41,000, France is like $37,000.
But Poland which is part of the EU is $12,000 as well. Russia is like $9000 per capita.
For all I know the numbers are totally made up, but they rate Russia at 17.29, China at 19.08, Poland at 26.56, Japan at 34.58, Germany at 36.54, France at 36.74 and the US at 37.98. Obviously the relationship to GDP per capita isn't monotonic, but some correlation appears to be there.

But China's labor is so cheap. Exploitation is a sweet sweet drug for the west. So, it's complicated.
Law propagation is done cynically via who benefits - either via influence and threats or mutual benefit. China would need to suffer from a lack of protection of their own to agree to the status quo which the west has become accustomed to. It is not a natrual state of being by any means.
Anyone who has suffered bullying and received a blind eye from society in return would know that despite the lofty claimed principles they never operate on equality, justice or other but power and what they can get away with.
China is already suffering from it. The golden age of them not giving a fuck about IP in hardware space are coming to an end, to detriment of the society at large.
Also, China has grown an upper class whose interests most strongly align with strong IP laws.
