Tensions grew over Senkaku Islands in between Japan and China

The uninhabited group of Islands Senkaku or Diaoyu turned up to be the cause for mounting tensions in between China and Japan. Japan on 11 September 2012 announced that they have purchased three islands of this group of islands from its identified Tokyo based Kurihara family (owner of the island) at $25b million. In response to this declaration, china sent two Marine Surveillance Ships for patrol and resettling Chinese claim on the islands. Chinese foreign ministry also warned Japan that necessary steps will be taken to protect Chinese interests to the issue.

 Following the study conducted by experts in 1968, the Island group that has been under the control of Japan, since 1895 holds oil reserves under the sea. China claims that the islands were discovered and controlled by them ever since fourteenth century and considers it to be a part of Taiwan (Republic of China).
