This link details the construction of the latest Chinese maritime/naval base being constructed on the shores of the Indian Ocean. China has a “string of pearls” strategy in which they are gradually creating a network of bases around the Indian ocean which can be used for either civilian maritime or military purposes in the future. The previous bases already built or activated are at Gwadar, Pakistan; Hambantota in Sri Lanka and a planned base in Myanmar (Burma). The latest Chinese base is going to be built at Bagamoto on the Tanzanian coast and a Chinese economic zone is also planned for that site.
Virtually under the world’s radar, Tanzania and China have developed a very strong commercial and military relationship. Tanzania also has natural gas deposits off its coast which China would like to exploit. India also has had longstanding relations with Tanzania so China is making an effort to squeeze out India’s influence in that nation.
These Indian Ocean ports (and airfields in the case of Gwadar as noted in a previous post) are being developed with initial civilian commercial usages in mind, but Chinese military assets are almost sure to be based at these ports in the future as China seeks to surround and “contain” India within its own Indian ocean sphere of influence. China is clearly not only trying to seize control of the South China Sea, but is also implementing a plan to control as much of the Indian Ocean as possible. This Chinese strategy is a direct threat to Japan, India, South Korea, the Philippines, Singapore, Taiwan, Vietnam, Malaysia and other Pacific Rim nations (the nations named in Ezekiel 38:13 as explained in my free articles, What Ezekiel 38-39 Reveal about a Future World War III and Japan’s Role in Prophecy). 
In the future, China could place warships, military aircraft, anti-missile defense systems and supersonic, long-range, anti-ship cruise missiles at these ports to not only negate India’s and NATO’s military power in the Indian Ocean region but also to seize control of the oil shipping routes that exit the Persian Gulf into the Indian Ocean to distant locations. When/if China places their military assets at these Indian Ocean locations, it will also obviously have in their gunsites the USA’s military installation at Diego Garcia Island in the middle of the Indian Ocean. The USA’s Pentagon warplanners better install extensive anti-missile and anti-warplane defense systems at Diego Garcia as that is an obvious target in China’s plan to create a system of bases to which its military assets can be quickly deployed.
