Populorum Progressio §52
Populorum Progressio: On the Development of Peoples
52 It is certainly all right to maintain bilateral and multilateral agreements. Through such agreements, ties of dependence and feelings of jealousy—holdovers from the era of colonialism —give way to friendly relationships of true solidarity that are based on juridical and political equality. But such agreements would be free of all suspicion if they were integrated into an overall policy of worldwide collaboration. The member nations, who benefit from these agreements, would have less reason for fear or mistrust. They would not have to worry that financial or technical assistance was being used as a cover for some new form of colonialism that would threaten their civil liberty, exert economic pressure on them, or create a new power group with controlling influence.
