other Asian nations, and the rapid associated growth in 
seaborne trade and energy that transits the Indian Ocean, is 
making the region increasingly significant. Approximately 
50% of the world’s container traffic and 70% of its 
petroleum shipments transit the Indian Ocean. The Indian 
Ocean littoral region encompassed 2.49 billion people in 
2010, representing more than one-third of the world’s 
population. It is estimated that by 2030 the population in 
the IOR will have expanded by 27%. An estimated 15% of 
the world’s fish catch comes from the Indian Ocean, and it 
may have additional hydrocarbon reserves that may further 
increase its strategic importance.      
China’s Expanding Presence in the IOR 
China’s developing strategic presence in the IOR is 
manifesting itself largely through port and infrastructure 
projects, and through its first regional military base. China’s 
development and investment projects have gained strategic 
 
coherence through Beijing’s Belt and Road Initiative (BRI).
