– CIMSEC – Zhongguo Haijing, or China Coast Guard (CCG) 2901, was not built to fight wars. At over 10,000 metric tons, it is by far the world’s largest constabulary vessel, a class of ship operating at the vanguard of China’s peacetime expansion in maritime East Asia. When it is commissioned sometime in the coming weeks, it will provide a huge advantage to China in the battle of wills taking place along its maritime periphery.
