Agree with Oceanic.
Also some rules you'd never think of. For example in a foreign reg GA aircraft we were only allowed a limited number of flights inside China. It was 6 or 8, can't remember. Most airspace is controlled by military, GA is an alien concept. Unless you're flying to large airports I'm not sure how you will stand language wise. We needed a nav for a lot of stuff. I wouldn't like to guess how Vfr microlights will be received.
Best of luck.
