Do people who have an immense interest in japan also have an interest in china?

Question:

Answer:

It depends on what is main driving factor of their interest in Japan. If their interests stems from anime and manga, they would most likely have less interest in China or other Asian countries. However, if the driving factor of their interest in Japan is the language, culture and the arts, then they will most likely be interested in China.

Once again, as the rest of the posters here have said, there is no way to tell accurately as it is based on personal preferences.
