This is the applicable section. I'm sorry it differs some from the one in the US that I am familiar with, but I'm not sure if this means you can go to any of these other countries for service, just that it is offered there for purchase, just like in the US. The easiest thing to do is check with the local Apple dealer and they can explain it.
7. General Terms
