The sanctions that were meted out to the members of the international human rights subcommittee of the standing committee that I mentioned were sanctions about travel to China and about financial dealings with China. That is, in itself, the sanction. It isn't a threat and it doesn't constitute foreign interference, because it's all above board. Canada does this all the time with respect to Haiti, Russia, Belarus and Iran.
The process of researching individuals in a different country and then later sanctioning them is part of how diplomacy and sanctions work. It is not in itself foreign interference.
