There are plenty of foreign hosts, the problem is that nobody knows about them. Gitee is a pretty big Chinese Github alternative, for example. Parts of the Russian software scene seems to prefer forums to dump software and source code.
You won't find these repositories looking for them, because they're often in their native language. Many forum posts are also locked behind registration. I've used Google Translate a bunch of times to get Russian software working, but only after someone linked it to me.
