This chapter, and the previous one, address, in an introductory manner and from the Colombian perspective, two fundamental questions that lie at the root of private international law and serve to understand its broad conceptual scope. The first question, which is dealt with in the previous chapter, refers to the national, international, and global dimensions of private international law, and the relevance it has when it is particularly considered in the latter perspective. Here, the focus is on the second question, which is not less vast and concerns the interactions between comparative law and private international law. In this regard, this chapter explores how some forms that the former adopts can be identified in the different ways in which the latter is practiced in Colombia.
