If Cuba is keeping millions of people in internment camps based on religion, or taking away freedom from once-free states (HK), or making expansionist claims, or outright threatening smaller democracies like Taiwan with war and destruction - then sure, Cuban cigars should be banned.

Myself? Against that particular type of banning, granted I can understand general economic reasoning even though I disagree. Now, banning one single brand of cigars even if they are following the law? Completely against that type of targeted banning, and I would immediately question the motives.

Same goes for Huawei or any company/product. You are allowed if you don't break the law. I don't care the origin, I care about the rule of [contestable] law over unilateral action. I may disagree with many laws, but I respect the process much more.
