Over the weekend, the largest anti-Japanese demonstrations in decades took place in China.
The cause? A chain of islands in the East China Sea, whose ownership is disputed between Japan and China.
The islands are uninhabited, but valued for oil reserves believed to be nearby; Japan recently bought the islands from their Japanese owners.
Chinese protested this weekend by vandalizing Japanese businesses and cars, and demonstrators pelted Tokyo's embassy in China with eggs and plastic bottles.
But experts on the region say the protests run much deeper than the islands.
