Language and country selector on a website

I'm currently designing a website for a global company with multiple market sites (website.com, website.co.uk, website.ru etc). Some markets also have multiple languages (website.be can be browsed in dutch, german and french for example).

The user should therefore have the possibility to change language within the same market site or change to another market site.

How do I achieve this without it being confusing to the user? Are there any good examples of how this can be solved?

I've done some benchmarking but most sites either have a country selector or a language selector, not both.
