The Guide to Sanctions is published by Global Investigations Review – the online home for everyone who specialises in investigating and resolving suspected corporate wrongdoing. We live, it seems, in a new era for sanctions: more and more countries are using them, with greater creativity and (sometimes) selfishness. And little wonder. They are powerful tools. They reach people who are otherwise beyond our jurisdiction; they can be imposed or changed at a stroke, without legislative scrutiny; and they are cheap! Others do all the heavy lifting once they are in place.
