United Nations peacebuilding activities are aimed at assisting countries emerging from conflict, reducing the risk of relapsing into conflict and at laying the foundation for sustainable peace and development.
Is the expression in bold present participle which is a complement to assisting countries emerging from conflict ? or is it an expression that must be considered as continuation of ... are aimed at' as with "assisting countries..." ? I think it must be present participle since laying the foundation for sustainable peace and development. takes at in front of it, making itself continuation of '...are aimed at'.
