As much as 50 percent of global oil tanker shipments pass through the South China Sea, which sees three times more tanker traffic than the Suez Canal and more than five times that of the Panama Canal, making the waters one of the world’s busiest international sea lanes. More than half of the world’s top ten shipping ports are also located in and around the South China Sea, according to the International Association of Ports and Harbors. As intra-ASEAN trade has markedly increased—from 29 percent of total ASEAN trade in 1980 to 41 percent in 2009—maintaining freedom of navigation has become of paramount importance for the region.
“This is a very important issue, and has become the main concern of Japan, the United States and even right now the European Union,” said Dr. Yann-Huei Song, a fellow at Academia Sinica in Taiwan. However, Yann-Huei says China is unlikely to instigate an interruption in traffic because its business, exploration, and importation rely entirely on freedom of navigation as well. Experts argue that the mutual benefits from regional economic integration provide an extremely compelling incentive for cooperation on resources, conservation, and security movements, according to a Harvard Quarterly paper.
