How to redirect GeoIP to another version of the site?

Question

htaccess

Installed the GeoIP module for redirects to another version of the site.
The task is this: redirect a visitor from non-CIS countries (site.com) to the site.com/world/ version. The
redirect works correctly, there are no problems.
But if a visitor tries to go to site.com, they will be redirected to /world/.
How to let the visitor switch to the main version?
