It seems that the effects of random events (trade bans, reduced / increased inflation) are not stored correctly - or even at all - in the EU saved game(s).
If you manage to get a trade ban to the rest of the world and save the game shortly afterwards, on reload the game will show up no trade bans.
If you want to keep the effects of the random events you should not load the game when they are in effect -- until a bugfix is applied.
