An active Chinese strategic presence in the Indian Ocean is no longer merely the stuff of speculation. India and other resident powers need to not only adjust to this reality but also exploit their geographic and diplomatic advantages to encourage China to operate in these waters cooperatively, not unilaterally. India could do this through a combination of further bolstering its own maritime capabilities, sustaining its capacity building for smaller island states, and deepening defense cooperation with such partners as the United States, Australia, Japan, France, and Indonesia. These steps could be augmented by the reinforcement of regional diplomatic institutions and visible efforts to engage China in security cooperation and dialogue, such as on transnational issues like search and rescue or noncombatant evacuations.This analysis begins with an assessment of China's expanding interests and presence in the Indian Ocean, followed by a summary of India's perspectives and responses. It concludes with some broad recommendations regarding the right mix of capabilities, posture, and partnerships for India to manage the impact of an inevitable Chinese role in its maritime neighborhood.China's Growing Presence in the Indian OceanSince early 2009, China has maintained a naval force to counter piracy in and near the Gulf of Aden. Chinese forces have also been deployed for noncombatant evacuations, notably in Yemen. Warships and submarines are becoming increasingly frequent visitors to Indian Ocean waters, making use of dual-use port infrastructure in Sri Lanka, Pakistan, and elsewhere. In addition, China is openly establishing a permanent military facility in Djibouti, and talk of a future network of access points or even overseas bases-a taboo idea just a decade ago-is becoming uncontroversial and commonplace in Chinese strategic circles. Unilateral combat exercises and, as recently as May 2016, counterpiracy exercises have occurred in the eastern Indian Ocean near Australia's island territories,1 while Chinese naval transits of Indonesia's Sunda Strait are becoming unexceptional.Given all these maritime activities, Xi Jinping's signature international initiative of the 21st Century Maritime Silk Road, while initially a geoeconomic project, will almost certainly have a security dimension that justifies an Indo-Pacific security footprint for China. The flag will follow infrastructure as well as trade.Much of this should not be a surprise. China has legitimate interests in the Indian Ocean. It is a great power and a trading economy enormously dependent on Indian Ocean sea lanes for its energy imports and container cargo. The predictability and security of this seaborne traffic are correspondingly critical to domestic economic, social, and thus political stability-indeed, to the survival of the Communist Party as the legitimate holder of state power. Accordingly, it would have been astounding if China had indefinitely outsourced the security of these critical sea lines of communication to the navies of strategic competitor the United States and U.S. allies and partners.Credible Chinese analysts such as You Ji (in this roundtable) are notably beginning to identify the contours of a Chinese Indo-Pacific maritime strategy, even if specific Indo-Pacific terminology is still treated with some wariness in China. The Maritime Silk Road, it could be argued, is proving to be the Indo-Pacific with Chinese characteristics.For other states, China's now-permanent presence in the Indian Ocean is cause neither for rejoicing nor despair. It is a fact. The question then becomes how other powers manage this historic shift in ways that protect and advance their own interests, as well as wider regional stability. A reasonable response would seem to be one that respects China's legitimate interests as an Indian Ocean power without harming the interests of others.A related consideration is the logic of engaging China as a provider of security public goods in the Indian Ocean. …
