All good examples. India, China, Italy, France.
Italy and France are heavily into football. But so are other countries that still manage to have a decent boxing tradition/ history.
India I don't know is good at any sport. It doesn't seem to be an important part of their culture.
China's a mystery. The most populated country on Earth... and their boxing history is pretty bland.

Also, look at Brazil and Argentina. South American neighbors... both big countries.
Football is huge in those countries. And yet Argentina has many times the boxing history/ tradition Brazil has.
I wonder why.
