Final answer:
Japan is the country that does not claim part or all of the Spratly Islands.
Step-by-step explanation:
The country that does not claim part or all of the Spratly Islands is Japan. While China, Vietnam, and Malaysia all have territorial claims over the Spratly Islands, Japan does not. Japan's involvement in the region has mainly been related to historical conflicts with China, such as the invasion of Taiwan and supporting Portuguese interference with China's trade.
