Context: China renewed calls for the Philippines to remove an ageing ship from a reef that Manila uses to press its stake in the Spratly Islands in defiance of Beijing's claim to nearly the entire South China Sea.
The move comes after the Philippines accused the China Coast Guard of firing water cannon against boats on a resupply mission to its garrison stationed on the grounded vessel at the weekend.
Spratly Islands
The Spratly Islands are a disputed archipelago in the South China Sea.
The archipelago lies off the coasts of the Philippines, Malaysia, and southern Vietnam.
It is claimed in its entirety by China, Taiwan and Vietnam, while portions are claimed by Malaysia and the Philippines.
The northeast part of the Spratly Islands is known as Dangerous Ground and is characterized by many low islands, sunken reefs, and degraded, sunken atolls with coral.
Economic activity has included commercial fishing, shipping, guano mining, oil and gas exploitation, and more recently, tourism.
