I used to wonder why Americans would go to "enemy" countries and teach people to speak our language--so they can spy on us later! I now see that conversational English in China probably isn't enough to significantly harm the Western world, and there's something positive to be said about cultural contacts with actual humans.
I've never really had an interesting in visiting the Far East, except perhaps for Ulan Bator, Mongolia. I don't know why I've always wanted to go to Ulan Bator, except perhaps because the name is cool. But anyway, now I think that China, in its vastness, might be an interesting place to visit. The band from the school at which I teach went on a junket (junket! get it??) to China this summer and was not only well received, but apparently they had a great time. So I've considered teaching English in China for a summer.
The internet search engines will return thousands upon thousands of hits for something like "teach English China". I read dozens of sites. I quickly determined that most places want you to teach for a year, but there are a few that will do a summer. I'm not sure how far I'm going to take this, but it's an interesting thing to consider. I'd like to do a teacher exchange to Britain in a couple years, too--we'll see what happens.
This week's Carnival of Education referred me to this blog post about teaching English in China. Organized, practical, and an easy read. If the topic interests you, start there.
