China’s growth as a maritime power has a direct effect on regional security. From claiming territory and building islands in the South China Sea, to establishing its first military base in Djibouti, Beijing is clearly out to increase its sphere of influence. The latest example is a naval base in Cambodia, constructed by China, not too far away from the Strait of Malacca, the crucial waterway between East Asia and the rest of the Indian Ocean. What is China doing? How is India responding? Images of a new base being constructed in Cambodia has striking similarities to the one in Djibouti. This represents a huge challenge.
