I wasn't saying i believe that New Zealand would declare war on China, but i do believe that they would in some way help India fight off China even if only a little bit. Plus the US has a military Pact called the watchful Eye with Australia, Canada New Zealand and the UK so if the US wanted to they could call support from New Zealand.
No offense to New Zealand, but I don't think they could do all that much. I've been down there (my best friend lives in Hamilton, and I visit her) and they seem like, really peaceful.
Secondly for the Philippines you would do well to accept "Philippines" on its own as an answer due to the fact most people don't ever write "the".
Thirdly for Myanmar also accept Burma as an answer. Although it is more and more recognized as Myanmar this site still uses Burma as a type in option.
Finally (personal thing) I don't see New Zealand getting involved in any war as they are generally very peaceful.
