Earlier this month, China declared new “baselines” round Scarborough Reef, a big coral atoll topped by a handful of rocks barely above sea stage within the South China Sea.
By doing so, China reaffirmed its sovereignty declare over what has develop into a world flashpoint within the disputed waters.
This was a pre-calculated response to the Philippines’ enactment of latest maritime legal guidelines two days earlier that aimed to safeguard its personal claims over the reef and different contested elements of the ocean.
This authorized tit-for-tat is a continuation of the continued sovereignty and maritime dispute between China and the Philippines (and others) in an important ocean space via which one-third of worldwide commerce travels.
The Philippines rejected China’s declaration as a violation of its “long-established sovereignty over the shoal”. Defence Secretary Gilberto Teodoro stated:
What we see is an rising demand by Beijing for us to concede our sovereign rights within the space.
Because the tensions proceed to worsen over these claims, there’s an ever-increasing danger of an at-sea battle between the 2 international locations.
What’s the Scarborough Reef?
Scarborough Reef known as Huangyan Dao in Chinese language and Bajo de Masinloc by the Philippines. It’s positioned within the northeast of the South China Sea, about 116 nautical miles (215km) west of the Philippine island of Luzon and 448 nautical miles (830km) south of the Chinese language mainland.
At excessive tide it’s diminished to a couple tiny islets, the tallest of which is simply 3 metres above the water. Nonetheless, at low tide, it’s the largest coral atoll within the South China Sea.
China asserts sovereignty over the entire waters, islands, rocks and different options within the South China Sea, in addition to unspecified “historic rights” inside its claimed nine-dash line. This consists of Scarborough Reef.
In recent times, the reef has been the scene of repeated clashes between China and the Philippines. Since 2012, China has blocked Filipino fishing vessels from accessing the dear lagoon right here. This prompted the Philippines to take China to worldwide arbitration beneath the United Nations Conference on the Regulation of the Sea (UNCLOS) in 2013.
Three years later, an arbitration tribunal dominated that China has no historic rights to maritime areas the place this may battle with UNCLOS. The tribunal additionally concluded China had “unlawfully prevented Filipino fishermen from participating in conventional fishing at Scarborough Shoal.”
China refused to take part within the arbitration case and has strongly rejected its ruling as being “null and void” and having “no binding pressure”.
What did China do that month?
China declared the precise location of the bottom factors of its territorial declare round Scarborough Reef with geographical coordinates (longitude and latitude), joined up by straight strains.
The declaration of so-called “baselines” is normal follow for international locations that wish to declare maritime zones alongside their coasts. Baselines present the place to begin for measuring these zones.
A rustic’s “territorial sea” is measured from this baseline outward to so far as 12 nautical miles (22km). Underneath the UNCLOS treaty, a rustic then has full sovereignty rights over this zone, protecting the seabed, water, airspace and any sources positioned there.
Nations need their baselines to be as far out to sea as doable to allow them to maximise the ocean areas over which they will reap financial advantages and implement their very own legal guidelines.
China is not any exception. Together with different international locations (particularly in Asia), it attracts essentially the most beneficiant baselines of all – straight baselines. These can join distant headlands or different coastal outcrops with a easy straight line, and even enclose nearshore islands.
China is particularly keen on straight baselines. In 1996, it drew them alongside most of its mainland coast and across the Paracel Islands, a disputed archipelago within the South China Sea. China outlined further straight baselines this March within the Gulf of Tonkin as much as its land border with Vietnam.
China says these actions adjust to UNCLOS. Nonetheless, its use of straight baselines round Scarborough Reef conflicts with worldwide regulation. It’s because UNCLOS gives a particular rule for baselines round reefs, which China didn’t observe.
Based mostly on our assessment of satellite tv for pc imagery, nevertheless, China has solely superior the outer restrict of its territorial sea by a number of hundred metres in two instructions. It’s because its straight baselines largely hug the sting of the reef.
These new baselines round Scarborough Reef are due to this fact pretty conservative and enclose a dramatically smaller space than the US had feared.

China’s declaration alerts that it might have deserted its a lot bigger “offshore archipelago” declare to what it calls the Zhongsha Islands.
China has lengthy asserted that Scarborough Reef is a part of this bigger island group, which incorporates the Macclesfield Financial institution, a completely underwater function 180 nautical miles (333 km) to the west. This led to concern that Beijing may draw a baseline round this whole island group, claiming all of the waters inside completely for its use.
The South China Sea arbitration tribunal dominated that worldwide regulation prohibits such claims. There shall be a collective sigh of aid amongst many international locations that China determined to make a a lot smaller declare over Scarborough Reef.
Significance and future steps?
Nonetheless, China’s clarification of its baselines across the reef alerts it might be extra assertive in its regulation enforcement right here.
The China Coast Guard has stated it would step up patrols within the South China Sea to “firmly uphold order, shield the native ecosystem and organic sources and safeguard nationwide territorial sovereignty and maritime rights”.
Given the lengthy historical past of clashes associated to fishing entry round Scarborough Reef, this units the scene for extra confrontation.
And what concerning the largest prize of all within the South China Sea – the Spratly Islands?
We are able to now count on China will proceed its lengthy straight baselines march to this island group to the south. The Spratlys are an archipelago of greater than 150 small islands, reefs and atolls unfold out over round 240,000 sq. kilometres of profitable fishing grounds. They’re claimed by China, in addition to the Philippines and a number of other different international locations.
These international locations will be anticipated to protest any tried encirclement of the Spratly Islands by new Chinese language baselines.
