Yes, I think that's a good question. I think it requires thinking about what ASEAN's limitations are and what it does.
I think what ASEAN does not do is resolve conflicts, so even within its own organization, it actually has challenges in resolving conflicts.
What it does do is keep dialogue open. The South China Sea has become a very complicated issue, partly because it also involves other major powers. The South China Sea is one of the most complicated disputes in the world, given the number of actors and the variations in terms of the types of claims that are made. The South China Sea is an especially challenging dispute to handle, so ASEAN is very challenged in terms of handling that.
What ASEAN does do for Southeast Asian states is provide mechanisms that allow for states to continue a dialogue on issues, including maritime questions with China as well as with the United States. In that sense, it is helping to maintain relations, but your point about it not being solved is certainly a fair one.
