In this sense PD is a long term effort while propaganda can be useful but it´s not the base for a long term relationship, and it can also harm this possibility

and manipulating others for a short term purpose. PD, as part of diplomacy, is on my view about building strong and sustainable relationships, which by definition entail understading and respecting each others points of vews and trying to find /build common ground based on mutual trust. In contrast, I understand propaganda as towards obtaining a specific result/ action from the other, not necessarily based on mutual trust and understanding but on imposing a certain interpretation/view as the correct and only one.
