I think that's a concept that is thorny enough to merit a word on what we mean by that. I personally don't know what it actually points at (is there any "free trade" ever happening in real life ?), or my naive interpretation would be trade with absolutely no rules, but I assume that's not what you're pointing at.
You definitely can. International trade has never been a fair field, power balance will be the most impacting element in the deal you get.
