Question regarding fannon Vs. Cannon

[http://users.livejournal.com/_wist_/]

I've been collecting loads of hetalia fanart and I've noticed how many characters seem to reappear in art done by different artists. My question is whether characters like Vietnam, Tibet and Cuba are Canon characters or just in the Fanon. Since I don't read Japanese I'm having a hard time figuring this out. If they are canon could anyone give me any info on them, that would be great.
ps: I really don't expect much info about Tibet

Thats wonderful news for me!
Do you know what was said about any of these characters by the way?
I'm surprised and interested that Tibet showed up.

Cuba is of course communist, likes ice-cream and sugar, abhors America, mistakes Canada for America all the time (but the two warmed up to each other after Cuba realized Canada is not in any way America or America's subordinate). According to Himaruya Cuba's bordering on having metabolic syndrome presumably due to sugar overintake :-)

Vietnam, Tibet and Thailand (the spiky bespectacled nation) are far less well-fleshed-out, so all one can say for now is that Vietnam is a boat girl, Tibet a Buddhist monk and Thailand a...spikily bespectacled.
