The Minister himself points that out [1].
While Chechnya is technically under Russian rule, in action it's basically a suzerain dictatorship under the son of a former rebel leader who defected to the Russians, but was given massive leeway and autonomy. And this is clearly an additional de-Russification method.
Turkey uses it as a pressure point on Russia as well [2], as a large portion of Turkey's population can trace their origins to refugees from the Russian Invasion of the Caucasus from the 1820s-1920s (eg. Erdogan's family), and even the Russian government recognizes it. Most of the infra there was built by Turkish companies closely tied to Erdogan (eg. Akhamat Kadyrov Masjid, the clock tower skyscraper, etc).
Also, because there are a bunch of braindead Redditors on here, Chechens are NOT ethnic Russian
