Rising China and emerging India are becoming major maritime powers. As they build large navies to secure their growing interests, both nations are roiling the waters of the Indo-Pacific—the vast littoral stretching from Africa to Australasia. Invoking a tale from Hindu mythology— Samudra Manthan or "to churn the ocean"—C. Raja Mohan tells the story of a Sino-Indian rivalry spilling over from the Great Himalayas into the Indian and Pacific Oceans. He examines the prospects of mitigating the tensions and constructing a stable Indo-Pacific order. America, the dominant power in the area, is being drawn into the unfolding Sino-Indian competition. Despite the huge differences in the current naval capabilities of China, India, and the United States, Mohan argues that the three countries are locked in a triangular struggle destined to mold the future Indo-Pacific.
