¿Por qué no los dos? I mean, if you actually go to developing nations you will see that they are investing into real infrastructure that improves the standards of living dramatically. They also intend to turn some profit off of it. Most likely much of that profit will be in building long-term economic relations, rather than immediate rent-seeking, which can be viewed as "trapping nations in debt traps", or as "investing into development". They also invest with much fewer strings attached compared to IMF, which is a win comparatively speaking.
