A new Pentagon map shows how China is beefing up what a top US general calls its 'dangerous position' in the South China Sea

• China and several of its neighbors have claimed parts of the Spratly Islands in the South China Sea.
• A map from a recent Pentagon report shows how those countries are building outposts in the Spratlys.
• While China's claims have been widely rejected, it continues to press them, at times aggressively

In November, the Pentagon released its annual China Military Power Report, which included a number of maps to illustrate its updated assessments of the Chinese military's capabilities and reach.
