LOL. You're reaching, Equation my friend, really reaching.
It's clear China is slicing more salami and wouldn't stop until she gets the whole enchilada. I'm sympathetic to China's historical LAND claims over South China Sea, Diaoyu Dao, and Japanese-occupied Okinawa, but no one owns the water.
One point. Ryukyu was an independent kingdom that was part of the Chinese tributary system but was never annexed nor conquered; China has as much claim to Ryukyu as she does over Korea and Vietnam.
