There is no need to read those languages. Translations are still a thing. I remember that, while on Reddit, r/Europe posted links in other languages, but OP provided an English translation. So, yes, you can post national news in your official language, whatever it is, and post its translation, and now you have an international community or instance.
But it seems I’m the only one who posts links in my official language (Spanish) on international communities.
