Beijing Exhibiting New Assertiveness in South China Sea - New York Times

MANILA â€" In tropical waters off the coast of the Philippines, a standoff between half a dozen Chinese fishing boats, two Chinese law enforcement vessels and an aging Philippine Navy ship recently attracted a lot of attention in Washington, Beijing and other capitals across Asia.

Superficially, the squabble was over some rare corals, clams and poached sharks that Philippine Navy seamen were trying to retrieve in early April from the fishing boats operating in the Scarborough Shoal of the South China Sea until two Chinese Marine Surveillance craft intervened. After two tense days, the Philippine ship â€" a refitted Coast Guard cutter sent by the United States last year to beef up its ally’s weak defenses â€" withdrew.

But the stakes were much larger, as the insistent claims ever since of sovereignty over the shoal by both the Philippine and Chinese governments made clear. The incident intensified longstanding international questions over the strategically critical, potentially energy-rich South China Sea that have become more urgent this year as the long-dominant United States and fast-growing China both seek to increase their naval power in the region.

“We’re just pawns,” said Roberto Romulo, a former foreign secretary of the Philippines who argues that China is flexing its muscles in a bid to gain unimpeded access to vast reserves of natural gas and oil believed to be buried under the South China Sea. “China is testing the United States, that’s all it is. And China is eating America’s lunch in Southeast Asia.”

More recently, a senior Chinese military officer even dismissed any legitimate role for the United States in the South China Sea. “The South China issue is not America’s business,” Gen. Ma Xiaotian, the deputy chief of general staff of the People’s Liberation Army, said in an interview broadcast Monday by Phoenix TV in Hong Kong. “It’s between China and its neighbors.”

The general’s statement appeared to throw down a challenge to the Obama administration, which has sought in the past six months to enhance United States military strength around the western Pacific and East Asia, where the South China Sea serves as an essential waterway for not only the United States Navy but also for a large portion of the world’s trade.

From placing Marines in the northern Australian port city of Darwin to increasing military relations with Vietnam, a country with an uneasy relationship with China, Washington has signaled its intention of staying, not leaving.

In the latest sign of its resolve to stand firm on Chinese assertiveness in the South China Sea, the administration sent Secretary of State Hillary Rodham Clinton and Defense Secretary Leon E. Panetta to testify last week before the Senate Foreign Relations Committee on the need for the United States to ratify the United Nations treaty that is intended to govern the world’s oceans.

China is one of 162 countries that has ratified the Law of the Sea treaty. But the United States has not done so, holding back from formal approval ever since President Ronald Reagan refused to sign it when it was completed in 1982.

A major goal of the joint appearance, administration officials said, was to strengthen the legal hand of the United States so that its navy can be assured the freedom of navigation that the treaty recognizes beyond any nation’s territorial limit of 12 nautical miles.

In contrast, Western diplomats say, China argues that freedom of navigation comes into force only 200 nautical miles from a nation’s coast, an argument that contravenes the Law of the Sea and, if put into effect, would basically render the South China Sea Beijing’s private preserve.

While China may have no interest in blocking shipping in the South China Sea, there is also no doubt that it has begun to project its power in the area. Vietnam, for example, claims that Chinese boats twice sabotaged oil exploration efforts last year by deliberately cutting ship cables in its waters. China said one of the cable-cutting incidents was accidental.

Meanwhile, China is expected to deploy its first aircraft carrier this year.

Two-thirds of the world’s natural gas trade passes through the waters of the South China Sea, according to a report by Yang Jiemian, president of the Shanghai Institutes for International Studies. The sea is the main passageway for oil from the Middle East to China, Japan, South Korea and the rest of Asia.

Now the sea itself is believed to hold a substantial reservoir of energy, with some experts predicting that under the seabed lies as much as 130 billion barrels of oil and 900 trillion cubic feet of gas.
