Whether they're linked is questioned. It has to be reviewed in the context of the agreement, the context of relations between the countries, and the only way to firmly establish it is survey methodology, surveying firms to prove that linkages have been there.
I did say there are cases where it's obvious historically, such as the ending of the slave trade. The slave trade was obviously tied to some of the most serious human rights violations. So it depends on the agreement, the countries, and the implementation.
