There's not much the FO can do.
Taking the approach that "we can't bankrupt them so we can't do anything" ignores the enormous range of different sanctions that are available.
For example, banning a large proportion of Russian athletes from the Olympics has certainly caused them to reconsider their approach to facilitating drug use by their athletes, and is a long way from severing all ties.
For example unrestricted travel, telecommunications connections and automated financial transactions aren't essential for trade, they are just a convenience, especially as foreign trade predates the Internet by thousands of years.
