The territorial dispute over South China Sea among China and its neighbors is being intensified with an increase in both a potential value of natural resources in the region and a strategic value of sea lines of communication.
The reason that I put among instead of "between" is to avoid ambiguity. For example, if i say "between," I thought the sentence means "China versus other neighbors allied".
I wanted to mean "China versus country A versus B versus C.. ." So, the question is, my usage is correct? If not, how can I edit this?
