It doesn't really matter how transparent it is, since, International Law has rather little ability to enforce its decisions. As much as we try to develop rules and norms to constrain and moderate behavior by countries in the international community, at the end of the day, "the strong [still] do as they can and the weak [still] suffer what they must". And yes, you're right that the actions and intentions are pretty transparent, with just some uncertainty surrounding the extent (ie, what reasoning will the PRC ultimately use to justify its claims, as it's also been quite ambiguous about them).
