Describe china and japans relationship with european countries

China and Japan both have an extremely rocky relationship with one another. Currently Japan shares democracy, human rights, and market economists with other European countries. Japan and European countries trade deals are currently running smooth. European countries are china's largest trading countries, and where they get most of there profit. China does not share any values or doesn't see eye to eye with any European countries and is on a thin string with America. (That's the simplest way I can put it)

Both countries had to aprove annexation.
