Which one of the following statements best reflects the issue with Senkaku Islands, sometimes mentioned in the news?

The correct option is "China and Japan engage in maritime disputes over these islands in East China Sea."

Explanation:

The Senkaku Islands (referred to as the Diaoyu Islands in China) are a group of uninhabited islands located in the East China Sea.
Both Japan and China (as well as Taiwan) claim sovereignty over these islands. Japan has administrative control over them, but China frequently contests this claim by sending maritime patrol vessels into the waters surrounding the islands, leading to ongoing bilateral tensions and maritime disputes between the two nations.

Why other options are incorrect:

1. They are natural volcanic islands, not artificial islands created in the South China Sea.
2. There is no permanent American military base established on these uninhabited islands.
3. The International Court of Justice (ICJ) has not declared them as "no man's land".
