First of all, I think the EU is getting more concerned about the assertiveness of China, but it is not paying really quite that much attention to the core strait situation. I think you can do both at the same time.
India takes the rise of China extremely seriously. They don't really trust the Chinese now, but where they will stand will be pretty opportunistic, particularly if we continue to have a Modi administration in Delhi.
Others in the region are concerned about China, but none of them want to be on the other side of China because they are likely to face punishment from the Chinese.
