Citing one line by Kevin23:
China’s mobile payments in 2018 were $12.8 trillion, US equivalent was $50 billion so a comparative 256x differential
Whilst China may not have a street crime problem like many Western nations have, it does have a problem with dishonesty - which is seen in everyday theft of property e.g. electric motorcycle batteries. Let alone the widespread corruption within officialdom; one spin-off is the neglect of industrial health & safety procedures, which can be lethal.

The Chinese economy as Kevin23 pointed out uses mobile payments on a scale not seen in the USA and I expect elsewhere too. Quietly in international crime-fighting forums acknowledges that fraud poses a big problem. Even only for example 0.5% is stolen, that is a lot of money.
