In this passage, the author mentions "the policy of good neighbor" and then defines it further as having "respect [for] himself and...the rights of others."
We know that the answer can't be parallelism because no group of words is actually repeated for any effect.
While "the policy of good neighbor" is put into different words for those who don't know the term, this is not to reinforce concepts, and so it's not repetition.
I would say the goal was more to clarify the term, which would be a restatement.
It is an analogy, either--the author says a nation's policy is defined by a certain ideal, but there is no strong or clear comparison made.
