Treaty ratios for an unaligned Pacific naval power

If a resource-rich, unaligned British-Isles-scale state existed in the Pacific, how would naval treaties treat it?

It would probably receive a ratio comparable to Japan's, which would make United States naval planners very uneasy.

Treaty negotiators would probably give the hypothetical state a ratio comparable to the Imperial Japanese Navy's because its resources and building capacity make it a major Pacific power. That outcome would greatly worry the United States Navy because it introduces another independent fleet of substantial strength. Comparable capability would earn treaty recognition without guaranteeing that the new state aligned with either established power. Geography, industrial capacity, and political alignment would all shape its arms-control status.
