Russia definitely has, just not as much in your backyard. China hasn't, but that's probably because the last time they tried that they got their ass handed to them by a country that had just been savagely attacked by (but also defeated) the us. Also it has been slowly encroaching on India and bhutan territory. China definitely declares it's intent to export it's style of polity around the world. And that does include torturing and disappearing citizens that are supposed to be on their own watch.
