$5 Trillion Meltdown: What If China Shuts Down the South China Sea?

July 16, 2016


China has fired off a music video, editorials and plenty of other propaganda, along with a few volleys from PLA Navy ships, in response to the international court ruling on the South China Sea, which it denounced as “null and void.” But after threatening to set up an air defense identification zone, what might the economic impact be if Beijing went one step further and closed off the entire area inside its so-called “nine-dash line”?

Based on a 1947 map by the then Kuomintang government, the vaguely defined nine-dash line encompasses around 90 percent of the South China Sea. It spans an area the size of Mexico extending more than one thousand kilometers from China, and which encompasses territory claimed by Malaysia, the Philippines, Taiwan and Vietnam.

While China is the major beneficiary of freedom of movement in the region, a number of other countries rely upon shipping routes through the disputed area, namely Japan, South Korea and Australia.

An estimated $5 trillion worth of goods are transported through South China Sea shipping lanes each year, including more than half the world’s annual merchant fleet tonnage and a third of all maritime traffic worldwide.

Oil transported through the Malacca Strait from the Indian Ocean, en route to East Asia via the South China Sea, is triple the amount that passes through the Suez Canal and fifteen times the volume that transits the Panama Canal.

According to Robert D. Kaplan, some two-thirds of South Korea’s energy supplies, nearly 60 percent of Japan’s and Taiwan’s, and 80 percent of China’s crude oil imports flow through the South China Sea.

Analysts estimate the cost of rerouting oil tankers via the Lombok Strait and east of the Philippines at $600 million per annum for Japan, and $270 million per annum for South Korea.

The majority of Australian cargo travelling through the South China Sea is destined for China; however, were China to obstruct shipping routes in the South China Sea between Australia and its other trading partners, it could force a costly reroute of some $20 billion worth of cargo per annum.

Oil and Gas Wealth

Another reason for China’s interest in the South China Sea is its massive potential for oil and gas—what Kaplan has described as a “second Persian Gulf.”

The U.S. Energy Information Agency estimates the South China Sea holds eleven billion barrels of oil—similar to Mexico’s total oil reserves and 190 trillion cubic feet of natural gas—enough to meet twenty-eight years of Chinese gas demand. The China National Offshore Oil Corporation has invested some $20 billion in attempting to prove its more optimistic estimate of 125 billion barrels of oil and five hundred trillion cubic feet of natural gas.

Should these estimates prove accurate—and there is some debate over the actual recoverable reserves—then the South China Sea could contain more oil than anywhere else on Earth, apart from Saudi Arabia
