What’s common between the transatlantic slave trade and fir trade

The Atlantic slave trade or transatlantic slave trade, also called slave trade, occurred throughout the Atlantic Ocean between the 16th and 19th centuries.

Founded in the 1960s, Fairtrade certification represents an initiative that brings together social responsibility, sustainability and competitiveness for small and medium producers.

Fairtrade Labeling Organizations (FLO) is a non-profit trading company based on social responsibility and whose purpose is to ensure fairness in international trade.

if interdependence implies a two-way dependence, and if each partner is equally dependent on the other for success, then there is an equal commitment to the making the partnership successful. the advantage is sustainability of the relationship, the disadvantage is that decisions are "democratic" and therefore may take longer to reach and more likely to be a compromise (which is not always the best solution). as the interdependence moves away from equality, the decisions become more influenced by the more independent partner. in the extreme the relationship becomes more dictatorial and more like "master-slave". generally the relationship has less commitment in both directions and is more likely to be temporary.

if one generalizes (and one shouldn't), equity partnerships, which is probably what is implied by interdependence, can be slow to progress or change but durable. the extreme alternative, independent-dependent partnerships tend to be efficient but more fragile.

hope this but you will have to site your own evidence. : )
