We have no border with them so whose (bigger) problem is that now? You'll see it the next years depending on which actors might want to engage with which goals
As long as you have such different foreign actors meddling there its going to stay like that.
Russia and China neither manage to control parts of their own territory in a benign in cooperative way. Only by heavy repression and population exchange.
Whats their plan for Afghanistan again except of bribing some factions? Build roads and bridges with thousands of foreign workers?
Heck their ally Pakistan is also deeply involved there and not for good you can believe me.
