Economic interdependence is studied in the theory of International Relations.
As other commenters have pointed out, interdependence is variously seen as preventing or leading to conflict. The former in the Liberalist school, when two countries both see war as too costly to their mutual interests. The latter in the Realist school, when interdependence is weaponized as a point of control or viewed as vulnerability.
The trade expectations model (Copeland) argues that high existing interdependence but declining expectations leads to conflict, while a statusquo that is relatively independent but with increasing expectations can be peace-inducing. I admit the expectations model is somewhat circular reasoning, cyclical really. Though it is statistically explanative of historical conflicts in the 19th and 20th century.
