That's kind of an extreme solution, and generally considered bad
practice.
That said, there are geographic RBLs, for example countries.nerd.dk
Here's what I do in SA:
describe BL_COUNTRY_CN_1 Mail client in China
header BL_COUNTRY_CN_1 eval:check_rbl('china', 'cn.countries.nerd.dk')
score BL_COUNTRY_CN_1 0.5
tflags BL_COUNTRY_CN_1 net
Substitute the ISO country code as needed.
If you want a hard reject, just move the DNSBL check into your MTA
with whatever reject message you like (assuming your MTA lets you
customize that for DNSBLs).

identify themselves with the people, have confidence in them,
cherish and consider them as the most honest and safe, although not
the most wise, depository of the public interests.
