This works especially well in continent games where they can't *really* get to your country easily. However, it'll work for just about any situation where you can't/don't want to be on the offensive but yet want them to not build other things.
So yes. What you need for this to work.
1) An enemy. 2) A stack of defensive-promoted units. You can bring along a few collateral-causing units. It'll only help you. 3) A ROP with a Civ that your enemy can easily reach and they also have a ROP with the neutral Civ. 4) A city your enemy can reach with the best cultural defense you can get.
The beauty of this plan, is they CANNOT bombard the cities defences, unlike if they neutral civ was your ally. Instead, they are left attacking a city with a 60% to 100% cultural bonus, and you can sit there virtually invincible till you're ready to strike back.
