Unfortunately, that is not the reality. China doesn't worry about India, Korea, Japan, Australia, there is only one power in their mind: America. If they can match US power in west Pacific, then the rest won't be a big problem. If they can't, the rest will be a question beyond their calculation.
So, the real problem is how much forces that US can deploy in this side of world. Last time, their Asia pivot policy requires 60% of military forces, it turns out to be unrealistic: they are a global power, concentrating so much power in one region for over years will risk losing her control of other region. So, now her policy is asking her allies to do more, these countries responses are: you first. So, we see that all Asian countries are keeping quiet among the China-US dispute in SCS: no local country wants to patrol SCS with US navy side by side. Instead, they start to improve their relationship with Beijing.
India's response is even more obvious: she will stay in IOC to resist the "Chinese threat". The last thing India wants is to get Chinese attention focusing on her alone because they know: Americans will not hesitate to sacrifice last Indian in fighting Chinese.
