Since when is China my enemy?

If there is a major nation on this planet that has never done anything bad to mine in its history I can think of is China.

I can remember American, British, French troops raping and humiliating that country, I can't remember a single time the opposite happened.

While China does not always play fair and there's plenty of despicable things they do I don't like, I just don't see them as my enemy and see no valid reason to do so.
