China's emergence as an economic power has been accompanied by an increase in its influence across the Pacific and Indian Oceans, with observers noting that the US has been the navy power on both seas since the Second World War.

Phuket is important strategically, on the Andaman coast and not far south of Burma, where Chinese investment and influence is growing.
India is also keen to assert its authority in the surrounding waters and Indian warships have also visited Phuket.

Read up on China's interest in having a "string of pearls" through the southern oceans. Thailand is after her own subs, too.
