Yup, the US gov't heavily restricts foreign sugar. This is just another excuse to exclude additional sugar. Also sugar is price fixed and not a true market commodity.

I grew up in a sugar beet region of the US. If you bring any of this up they say that sugar needs to be protected and yadda yadda yadda. They bitch about everything the gov't does, except when it comes time to hand out those subsidy checks.
