Obviously, the sanctions regime is not working. There are things that can be done. The most obvious and simplest one is better regulation of crypto. Twenty-five per cent of crypto use is by criminals. Criminals are unusual.... In the same way as people who are busting sanctions on behalf of Russia, they don't mind if they lose money. People are always horrified about how volatile crypto is. If you are a criminal or a sanctions-buster, you don't care how much money you lose. This is, of course, why crypto currencies haven't gone away. They should have gone away in terms of economic logic. That's the first thing.
Obviously, the second one is better regulation of tax havens.
The third thing goes back to your Kyrgyzstan point, which is having a better understanding of how value chains work. This is a bit of a sideline, as I had a significant British research grant a few years back looking at trying to improve accounting down supply chains.
I think the three things are practicality, improved accounting down supply chains and having much tighter restrictions around the flow of money. It can be done.
