Seriously? Chinese and Japanese mixing? That'll take some kind of insane profet who manages to convince them that the West has to be exterminated at all costs. Barring that or an alien invasion , it's not particularly likely that those two particular nations would actively work together.
Also, to Schemer - what I'm personally doing is learning the world's most spoken languages, and if I complete that list then I'm going to move on to the list I want to learn just cuz I like how it sounds.
So far I speak English, French, Spanish, Russian and Bulgarian. The last one I know because I grew up there. Russian in part because of mixed heritage. My French is of the Quebecois variety, naturally since I live in Quebec, Canada. Although I'd much rather be hearing and speaking the European variety, if I have to be blunt about it. My Spanish has become rusty because ever since I arrived in Canada, I have to speak English and French predominantly. Latinos congratulate me (in a rather surprised fashion) of my good handling of the Spanish language and then tend to stubbornly avoid talking to me in that same language, instead relying on the two official languages of Canada (of which only one is the official for Quebec, and you can guess which one).
I have done superficial attempts to learn German and more importantly Scottish Doric, will have to get back on those in the future.
Basically what's left of the list of obligatory languages is Mandarin and Arabic. On which I should get started within the next year.
Then the list of 'for fun' includes the aforementioned German and Doric, along with Romanian, Australian and Japanese; because while I'm not a huge fan of anime and manga, I still think the language is interesting.
