This doesn't explain why Roman decided to steal Dust from the capital itself. If he wanted to conduct a low key operation like a localized terrorist attack, It makes more sense to orchastrate a steady chain of robberies across the continent to mask his intent. Also if he has a strong economic power at his back, why can't he just buy the Dust he needs?

For my two cents, I think the Dust is just a pleasent extra he can scoop up while executing his actual plan. What that goal is I have no idea, its hard to speculate without knowing what his objective is. Here are a few theories though.

1) Someone is trying to discredit Dust.  A manufacturing company like the Schnee Dust Company thrives on a high level of demand, and if Dust was proven to be too dangerous, it would make room for another company to provide a safer, cheaper alternative to Dust.

2) Waking the world up.  The Grimm might even now be regaining their strength, but nobody wants to commit to fighting them again considering their utopian lifestyle.  This might be the slap in the face the world needs to understand they are still vulnurable.

3) A excuse for war.  Since the school has a international list of students, it could be a nation wants to make a excuse to pull its students from the academy and bar relations.

As I said its hard to know for sure unless we know what the endgoal is to this plan, but these are just a few points of specuation.
