Sino-Japanese relations and more

Wikipedia Today we have been adding on request some country-specific categories, like the sino-Japanese relations. We did have already a section on 'international relations', but with some exceptions (like William Overholt) that description was too vague, we discovered. We have been adding section on Africa, the USA, India and Japan.
Europe is still missing as a section: we will have to look into that shortly. Do let us know if you have more suggestions.
