The US navy has increased its training exercises off the coast of Thailand.
The new drills are part of a strategic campaign which the White House calls its "pivot to Asia", but others see the rise in military activity as a political move by the US to flex its muscles.
It comes at a time of deep tension over territorial disputes surrounding the group of islands known as the Scarborough Shoal.
