South China Sea has been “apple of discord” between US and China in international affairs for decades. Not only US-China rivalry but also regional countries have been motivated to involve on the territory as it’s one of the lucrative territories in both geopolitical and strategic dynamics. People who are interested in international affairs and geopolitics must stay with the news over the South China Sea. Now, it has become a global issue even small countries are involving vis-à-vis position. Philippine already has gone to Permanent Court of Arbitration against China and the court verdict in favour of its claim. Thus, it is said that South China Sea could be the battleground of World War III. To understand the statement we have to have a particular knowledge of the issue and have to look at the geopolitical and strategic importance of South China Sea.

Geographical location of South China Sea:

The South China Sea is a marginal sea of Pacific Ocean having the area of 3,500,000 square kilometres situated on the south of China; east of Vietnam and Cambodia; northern-east of Malaysia; west of Philippine and up to the Strait of Malacca. The South China Sea is collectively an archipelago of thousands of corals, reefs and small islands. Major rivers that flow into the South China Sea are Mekong, Red, Pearl, Min, Jiulong, Rajang, Pahang, Pasig etc. the islands situated in the area are Spratly Island, Paracel island, Prata’s island, Scarborough island, Macclesfield island etc.

Geopolitical Landscape of South China Sea:

Geopolitical location is the most crucial importance of South China Sea. To categorize the geopolitical context, we can identify these points-

The South China Sea is the sea route for 50% global trade.

It’s the territory where a vast number of gas, petroleum and mineral resources are preserved.

It’s the area of having enriched seafood.

In today’s world, energy consumption is one of the most geopolitical dynamics in international relations. Developing countries need to secure their energy supply to continue their growth and developed countries can’t think a moment without redundant energy. So, oil and gas are very important. Let’s see the oil and natural gas consumption. It’s estimated that the South China Sea reserves 7 billion barrels of oil, 900 trillion cubic meters of natural gas. The Zhujiang river basin, Signage Sea basin, Bieber Gulf basin, Zengmu basin contain averagely four oil generation layer systems and 0.5 to 5 billion oil reserves. There are some other valuable materials like Ilmenite, Monazite, Zircon, Cassiterite, Arenaceous quartz etc. these are very important raw materials for industries. The South China Sea is rich in salt also. The annual output of salt is estimated 604,000 ton.

Another importance of South China Sea is that it is the one-third trade passage of global maritime passage. It is the link between the Pacific Ocean and the Indian Ocean. Malacca Strait is the cheap sea passage of Persian Gulf. Thus it became important for US, China, Japan, Korean Peninsula and East Asian countries. For example, 60% of Japan and 80% of China’s oil imports through this from the Middle East.

The seafood is also a crucial cause of the importance of South China Sea. The South China Sea covers 12% of global fish products. China, Philippine, Vietnam etc produce a huge number of fisheries resources.

Strategic Landscape of South China Sea:

While geopolitics indicates geographical relations with politics, there is another importance which is strategic. The power politics, military interests created the South China Sea more important. Today’s world is the US leaded where China is a rising giant economically and politically. The US must have to keep an eye on the South China Sea to check China. Besides, South China Sea is the route of US military supply to the Middle East.

If we evaluate US interest in the South China Sea, we can identify two specific subjects here. First, US access to trade and military purpose and second are to check Chinese hegemony. When South China Sea covers 5.3 trillion $ shipped through it, 1.2 trillion $ of this of US. With 700 billion GDP and the population of 525 million, South East Asia is the 5th largest trading partner of US.

Besides, US has several joint military bases in this area. It is said that the US has more than 60 military bases in Japan; about 40 in South Korea and it has several treaties with India, Philippine and some other countries. That’s why the US keeps a cautious eye on this. In October 2015 US warship passed within 12 nautical miles of China.

On the other hand, China claims 90% areas of South China Sea. By de facto, it controls a large portion of the areas. It is the 2nd oil consumer of the world after the US but it has to import half of the demand. The political strategy of China on the South China Sea is to maintain its status quo over there. Because China already has a dispute with Japan over Paracel & Spratly islands. And China knows properly that western powers are considering “China Threat” after cold war since 1990. In addition, Taiwan is another headache for China. Thus China is having a dominating image with neighbours and made surface-to-air defence system. In 2013 it started to build artificial islands in the South China Sea.

The concept of Exclusive Economic Zone could be another clash between China and its neighbours. By the UN Convention on the Law of the Sea (UNCLOS) country has control over 200 nautical miles as EEZ. It becomes problematic when the baseline is accounted from reef and rocks.

Besides US-China tension Japan, Philippine, Vietnam, Indonesia has its own interest in the South China Sea. Japan, Philippine and Vietnam has become “strategic partner” on South China Sea issue. On June 2015, Japan and Philippine signed the Joint Declaration on the Strengthened Strategic Partnership and they conducted their first joint naval exercise in the South China Sea. Japan also took Vietnam as “strategic partner” as Japan promised Vietnam ODA package on technical support. On August 2016 Vietnam sends rocket launcher to the South China Sea.

Another neighbour Australia is also not immune from South China Sea conflict. The Labor Govt. also announced to display defence force to conduct freedom of navigation.

Association of South East Asian Nations (ASEAN) tried to have multilateral dialogue in Vientiane, Laos. 10 members along with United States, China and six other nations: Russia, India, Japan, South Korea, Australia and New Zealand expressed the importance of peace and stability in the South China Sea.

Conclusion:

The famous geopolitical theorist Alfred T. Mahan once theorize that to control world power state have to have control over the sea. Though air defence and ballistic missile system questioned the theory, the importance of sea didn’t decrease its importance. Cheap business pathway, huge consumption of oil, mineral resources, and blue economy is the crucial dynamics of geopolitics and strategy. That’s why South China is important in geopolitics and strategy.
