When three Chinese scientists plunged to the bottom of the South China Sea in a tiny submarine early this summer, they did more than simply plant their nation’s flag on the dark seabed

The men, who descended more than two miles in a craft the size of a small truck, also signaled Beijing’s intention to take the lead in exploring remote and inaccessible parts of the ocean floor, which are rich in oil, minerals and other resources that the Chinese would like to mine. And many of those resources happen to lie in areas where China has clashed repeatedly with its neighbors over territorial claims.

After the flag planting, which was done in secret but recorded in a video, Beijing quickly turned the feat of technology into a show of bravado.

“It is a great achievement,” Liu Feng, director of the dives, was quoted as saying by China Daily, an English-language newspaper, which telegraphs government positions to the outside world.

The global seabed is littered with what experts say is trillions of dollars’ worth of mineral nodules as well as many objects of intelligence value: undersea cables carrying diplomatic communications, lost nuclear arms, sunken submarines and hundreds of warheads left over from missile tests.

While a single small craft cannot reel in all these treasures, it does put China in an excellent position to go after them.

“They’re in it for a penny and a pound,” said Don Walsh, a pioneer of deep-ocean diving who recently visited the submersible and its makers in China. “It’s a very deliberate program.”

The small craft that made the trip — named Jiaolong, after a mythical sea dragon — was unveiled publicly late last month after eight years of secretive development. It is designed to go deeper than any other in the world, giving China access to 99.8 percent of the ocean floor.

Technically, it is a submersible. These craft differ from submarines in their small size, their need for a mother ship on the surface, and their ability to dive extraordinarily far despite the darkness and the crushing pressures. The world has only a few.

Jiaolong is meant to go as deep as 7,000 meters, or 4.35 miles, edging out the current global leader. Japan’s Shinkai 6500 can go as deep as 6,500 meters, outperforming craft “all over the world,” according to its makers. Russia, France and the United States lag further behind in the game of going deep.

American experts familiar with the Chinese undersea program say it is unusual in that Beijing has little experience in the daunting field. As a result, China is moving cautiously. Jiaolong’s sea trials began quietly last year and are to continue until 2012, its dives going deeper in increments.

“They’re being very cautious,” Dr. Walsh said. “They respect what they don’t know and are working hard to learn.”

In an interview, Dr. Walsh said that the Chinese were especially interested in avoiding the embarrassment of a disaster that ends with the aquanauts’ entrapment or death. “If I’m the new kid on the block,” he said, “I’m going to make sure that I’ve got bragging rights.”

Still, China is already waving flags. The move resembles how Russian scientists, in the summer of 2007, plunged through the ice pack at the North Pole and planted their flag on the bottom of the ocean. Upon surfacing, the explorers declared that the feat had strengthened Moscow’s claims to nearly half the Arctic seabed.

Wang Weizhong, a Chinese vice minister of science and technology, said that the Jiaolong’s sea trials “marked a milestone” for China and global exploration. The recent successes of the craft, he said in late August at a news conference in Beijing, “laid a solid foundation for its practical application in resource surveys and scientific research.”

But at least one senior Chinese expert questioned what he called “the current propaganda.” The expert, Weicheng Cui, a professor at the China Ship Scientific Research Center, which is building the submersible, said Thursday in an e-mail that the craft’s sea trials had steered clear of contested islands “to avoid any diplomatic issues.”

The flurry of publicity over the flag planting, he said, “is not so helpful for us to complete the project.”

China’s splash in the arcane world of submersibles comes after years of singling out major industries and technologies for rapid development. China is rushing to make supercomputers and jumbo jets. With expanding political ambitions and territorial claims in neighboring seas, it has paid special attention to oceanography and building a blue-water navy, one that operates in the deep waters of open oceans.

The United States once held the submersible lead. In 1960, it sent Dr. Walsh, then a Navy officer, to the ocean’s deepest spot, seven miles down. But over the decades, it lost its edge to France, Russia and, most recently, Japan.

China began its push in 2002. A few Westerners became aware of the guarded effort when China ordered from Russia the forging of a spherical hull about seven feet wide.

At the heart of any submersible lies the hollow sphere where the aquanauts work. It houses a pilot and two observers, who can peer out of tiny portholes. Typically, a dive into the abyss is an all-day affair, requiring hours to and from the bottom.

American experts said China went on a global shopping spree to gather sophisticated gear for its submersible. From the United States, it bought advanced lights, cameras and manipulator arms. Dr. Cui estimated that 40 percent of the craft’s equipment came from abroad.

China also turned to the United States for tutoring. In 2005, five Chinese trainee pilots and one scientist participated in eight dives on Alvin, the oldest and most famous of the world’s deep-diving craft, which is run by the Woods Hole Oceanographic Institution on Cape Cod. China “bought time on Alvin to gain experience,” according to the Deep Submergence Science Committee, a group that advises the federal government and universities on ocean exploration.

Though Alvin can go down only 4,500 meters, or 2.8 miles, it has made thousands of dives and discoveries, and is widely seen among experts as highly productive and well run.

One of the Chinese trainees was Ye Cong, now a pilot on Jiaolong during its sea trials.

Last year’s tests went as deep as 1,000 meters (about a half mile), and this summer’s as deep as 3,759 meters. Next year Jiaolong is to dive to 5,000 meters and in 2012 reach its maximum depth.

Dr. Walsh said the flag issue prompted more awkwardness than swagger among those who are building and testing the new submersible.

“We had a laugh about it,” he recalled of his China visit. “I said, ‘Oh, you’re copying the Russians,’ and they kind of giggled. These guys are pretty apolitical and pretty well insulated” from Beijing. “They’re just contractors doing their job.”

Red Dragon should first return the Vietnamese islands, then attempt for going deep in to the ocean.

TRed Dragon is on a learning curve, be it through purchasing needed sensitive and otherwise unavailable equipment locally or through covert means.

When they feel they have reached their goal of self-sufficiency in all the major fields, then they will show and flex their muscle.

Countries such as India that has lulled themselves to sleep with the "India Shining" feeling would get a very rough kick from the dragon.

When the dragon decides to breate fire, all those countries who have given it a foothold in the 'string of pearls' move will only be too subservient to follow the dragon's commands.

Won't it be too late then for us? We have been all the while followers, not initiators in any specific endeavour. While we indulge in our passionate pastime of debating on anything and everything, serious or trivial, our enemies move on leaving us way behind.

The IT revolution has brought India its much needed economic clout but can we be complacent now that others are as competent as we are. They, read China, has upped the ante by becoming the world's super hacker. As reactive as usual, we have just set up a unit to counter their move.

When will be become pioneers and leaders in any field?

How long before they start planting flags in the Indian Ocean as well? If they can get away with doing this in international and disputed waters India should start doing the same: asking for more imports won't solve our oil and gas shortage.
