Do the "main-sub" banks in different countries share information if one of them in non CRS country?

VTB bank. It’s a Russian bank. It also exists in Armenia. Russia is a CRS country, Armenia isn’t.

Will a VTB bank in Armenia share info with VTB in Russia if a russian citizen opens an account in VTB Armenia? I mean, any russian citizen who opens such an account. Not necessarily the russians those who live in Russia permanently – tax residents.
