Is China tightening the noose on countries it considers hindering its goal of dominating the South China Sea?

Beijing's blockade of Scarborough Shoal and the recent harassment of Philippine resupply missions to Marines manning a dilapidated ship outpost on Ayungin Shoal are just recent instances pointing to this.

While they are considered part of the West Philippine Sea, Beijing believes these outcrops are historically part of Chinese territory under what it now claims is the 10-dash line as shown on its latest map covering nearly the entire South China Sea.

The disputed waterway has long been a source of tension and dispute among neighboring countries in the region, with China at the center of it all because of its expansive claims.

Scarborough Shoal, known as Huangyan Island to China and Panatag Shoal to the Philippines, covers a relatively small area of only about 150 square kilometers, but it holds immense importance due to its abundant fishery resources.

Ayungin Shoal, on the other hand, is strategically located, being only a few kilometers off Palawan, and it could be a vital launch pad for an attack on the Philippines.

Tightening the noose around these two shoals could be part of a broader strategy to establish control over the South China Sea. These outcrops could be used to monitor and restrict the movement of ships in the area and effectively limit the activities of the other claimant states.

China's blockade of Scarborough began in 2012 when it seized control of the atoll after a standoff with the Philippines. This move ignited a diplomatic and geopolitical firestorm. The Philippines argued that Scarborough Shoal is well within its exclusive economic zone as defined by the United Nations Convention on the Law of the Sea.

China, on the other hand, claimed historical rights to the area, which has been a longstanding point of contention. The foremost repercussion of China's blockade has been its severe impact on Filipino fishermen.

They have been routinely denied access to the waters around Scarborough, effectively cutting off their livelihood. The blockade has led to a sharp decline in catch sizes and income for these fishermen, forcing many into poverty.
