It's the classic tale of David versus Goliath. Wallonia is the French-speaking region of Belgium.
The European Union has a population 99 percent larger. But Wallonia appears to be winning its argument.
The tiny population has rejected a trade deal between Canada and the EU, known as the Comprehensive Economic and Trade Agreement.
In doing so, Wallonia derailed an agreement seven years in the making - which has the approval of every other country in the EU.
Opposition to the deal spread across Belgium after Wallonians complained.
Although Belgian government leaders support the deal, they say they can't approve it without support from the people.
So will the deal be renegotiated? And how does it affect the worldwide reputation of the EU?
