Reading about other countries and people from other places is a great place to get kids interested in the world and travel. Of course, there are all sorts of books and stories written by authors from all ove the world to choose from, but something many kids (both young and slightly older) might enjoy are fairy-tales, folk tales, and mythology from different countries and cultures.
There's a wealth of these kinds of tales available both online and in paper book-form. Here are some great links to access some of that material that you can access with your child. To me, this is a great way to explore the world with your children through stories and books.

This website provides reading tips for tales and stories from countries all around the world, and you can also read some of classic folk-tales (like HC Andersen and Aesop's fables) right on the site. There are links to audio fairy-tales, and animated tales as well. It's a great resource with tons of links and tips.
