By the numbers of speakers, it would be the Chinese
By cultural popularity (in the west), it would be the Americans
By originality/creators, it would be the English
I personally lean towards the English owning it since it's the __ENGLISH__ language. Even as an American it is not a great feeling to see the original language modified so flippantly. I guess I'd prefer to be speaking the "American flavor of English" and have true Standard English be defined by the UK.
I get that languages change over time and the true owners of a language are the speakers, diluted times the number of speakers of that language, but still it's something I like to think about.
