Hmm. As a Brit I would not consider a trip to Paris to be "tourism". It's just a trip over the border. Yes they speak a different language there but it's a language that I was forced to study in school. No doubt Germans feel the same way.

Going to Spain on the other hand would be tourism. I don't speak Spanish, it's not a neighbouring country, you arrive in an airport, etc.

If an American or a Chinese person goes to Paris I feel they likely have different motivations and itinerary than a Brit, Belgian, etc who is taking the train possibly only for the day.
