Remember the island disputes between Japan and China when Obama pushed for the Pivot to Asia? Japan listened and trade dropped like a rock between the two. Something like 70% of what Japan exported from China was actually Japanese companies that outsourced so it didn't really cost China except for the cheap labor Japan was paying Chinese to make their products. But Japan was hurt more because not only they didn't have their products to sell to make money, their exports to China were Japanese products that Chinese consumers bought and Japan went into a recession while China hardly felt a thing. The US and the West didn't come to help Japan but instead exploited Japan's misfortunate and tried fill any gaps in trade that Japan lost. The Japanese were so angry that later when Obama called for the US, Japan, South Korea to jointly take on China, Japan instead decided to piss-off South Korea effectively ending Obama's Pivot to Asia.
