Johnson says that "this is the first tranche of what we are prepared to do". In addition, there will also be asset freezes to the three supposed high-net worth individuals (Gennadiy, Nikolayevich, Timchenko).

Again, these sanctions are built off the supposed narrative that the UK still doesn't see the Donbass situation as being an "invasion". Go figure.
