It's good that it's back to business for China and Japan. Abenomics is a dismal failure and Abe certainly can't afford to have wayward political extremists angering his biggest trading partner at a time when China is amenable to putting the Diaoyu issue on the backburner.
China and Japan will get back to making money and that's good for both sides.
This is a strong warning to Vietnam and Philippine. You gain nothing for going against the growing China.
