This thesis considers whether donor countries that contribute with foreign aid to a recipientcountry also contribute with peacekeeping troops. The question is premised on the idea thatforeign aid serves as a proxy for national interest. Employing rigorous regression analysis witha high-dimensional fixed effects linear estimator, the study analyses a comprehensive datasetof country dyads that covers 30 year (1990-2019) and comprises 157 donor/origin countriesand 43 recipient/destination countries. I find a positive and significant relationship betweenforeign aid and troop, indicating that that sending foreign aid to a country is positivelyassociated with an increase in sending peacekeeping troops to that country.
