China launches first aircraft carrier on maiden sea trial

  China's first aircraft carrier held its sea trial on Wednesday, a step likely to stoke patriotic pride at home and jitters abroad about Beijing's naval ambitions.

The long-awaited debut of the vessel, refitted from a former Soviet craft, marked a step forward in China's long-term plan to build a carrier force that can project power into the Asian region, where seas are spanned by busy shipping lanes and thorny territorial disputes.

"Its symbolic significance outweighs its practical significance," said Ni Lexiong, an expert on Chinese maritime policy at the Shanghai University of Political Science and Law.

"We're already a maritime power, and so we need an appropriate force, whether that's aircraft carriers or battleships, just like the United States or the British empire did," he said in a telephone interview.

The carrier "left its shipyard in Dalian Port in northeast Liaoning province on Wednesday morning to start its first sea trial," said the official Xinhua news agency, describing the trip as only a tentative trial run for the unfinished ship.

"Military sources said that the first sea trial was in line with the schedule of the carrier refitting project and would not take a long time," the agency said.

The aircraft carrier, which is about 300 metres (984 feet) long, ploughed through fog and sounded its horn three times as it left the dock, Xinhua said on its military news microblog.

In an interview published this week, Chinese navy Rear Admiral Yin Zhuo said his country intended to build an air carrier group, but the task would be long and difficult.

"The aircraft carriers will form a very strong battle group," Yin told the China Economic Weekly. "But the construction and functional demands of an aircraft carrier are extremely complex," he told the magazine.

Training crew and, eventually, pilots for the carriers was a big challenge, said Yin.

PRESTIGE AND POWER

Last month, China's defence ministry confirmed the government was refitting the old, unfinished Soviet vessel bought from Ukraine's government, and sources told Reuters it was also building two of its own carriers.

"One of the biggest drivers behind this is prestige," Ashley Townshend at the Lowy Institute for International Policy in Sydney .
"The Chinese debate on sea power has been focused on its coming of age as a great power, and great powers have great navies, and great navies have aircraft carriers," he said.

If Beijing was serious about having a viable carrier strike group, it would need three carriers, said Townshend.

China would also have to develop support ships and aircraft for any carrier group, he said, noting it would take some 10 years to develop a viable carrier strike group.

In China's neighbourhood, India and Thailand already have aircraft carriers, and Australia has ordered two multipurpose carriers. The United States operates 11 carriers.

Earlier, a Pentagon spokesman played down the likelihood of any immediate leaps from China's nascent carrier programme.

But that is just one part of China's naval modernisation drive, which has forged ahead while other powers tighten their military budgets to cope with debt woes.

China has been building new submarines, surface ships and anti-ship ballistic missiles as part of its naval modernisation.

The country's growing reach at sea is triggering regional jitters that have fed into longstanding territorial disputes, and could speed up military expansion across Asia.

In the past year, China has had run-ins at sea with Japan, Vietnam and the Philippines. The incidents -- boat crashes and charges of territorial incursions -- have been minor, but the diplomatic reaction often heated.

Last week, Japan warned that China's naval forces were likely to increase activities around its waters, prompting Beijing to accuse Tokyo of deliberately exaggerating the Chinese military threat.

"This is showing to the whole world that China's maritime mobility is expanding drastically. This is showing that China is in the process of acquiring capability to control South China Sea as well as East China Sea," said Yoshihiko Yamada, a professor at Japan's Tokai University about the carrier trial.

China's defence budget has shot up nearly 70 percent over five years, while Japan, struggling with public debt, has cut military outlays by 3 percent over the same period, a Japanese government report said.

A senior US Navy intelligence officer earlier this year said he believed China wanted to start fielding multiple aircraft carriers over the next decade, with the goal of becoming a global naval power capable of projecting power around the world by mid-century.

"A single, solitary aircraft carrier floating on the sea, without the accompanying forces, doesn't constitute a battle force," said Ni, the Shanghai professor.

Archaeopteryx may not have been a bird, but just a feathery dinosaur


Archaeopteryx: The creature long believed to be the earliest known bird may not have been a bird at all, suggests a new Chinese fossil find.

This artist's rendition released by Nature shows what scientists at Chinese Academy of Sciences in Beijing are dubbing 'Xiaotingia zhengi.' The discovery of its fossilized remains helped scientists propose an evolutionary tree that suggests archaeopteryx is not a bird.










The legendary winged creature long known as the earliest bird, Archaeopteryx, might have just been dethroned, scientists reveal.
Instead, a newfound fossil from China suggests Archaeopteryx was not a bird after all, but one of many birdlike dinosaurs, a finding that could force scientists to rethink much of what they thought they knew about the origin and evolution of birds.
watch now







Archaeopteryx lived about 150 million years ago in what is now Bavaria in Germany, back when EuropeDarwin's theory of evolution published just two years before the fossil discovery. Its place as the earliest and most primitive known bird made it central to the scientific understanding of the evolution of birds and flight.  First discovered 150 years ago, the carnivorous fossil, with its blend of avian and reptilian features, seemed an iconic evolutionary link between dinosaurs and birds, bolstering
Still, for decades, there have been doubts as to whether Archaeopteryx was really a bird.

Trading places
Now scientists have uncovered a new fossil in China whose combination of features unexpectedly suggests Archaeopteryx was actually just a relative of the lineage that ultimately gave rise to birds.
The novel chicken-size fossil in question, Xiaotingia zhengi, dates back about 155 million years. The carnivore was found in Liaoning in China, where many other extraordinary specimens of feathered dinosaurs and early birds have been unearthed. (The species is named after Zheng Xiaoting, who helped establish the Shandong Tianyu Museum of Nature as a repository for vertebrate fossils from China.) 
To see where X. zhengi belonged evolutionarily, paleontologist Xing Xu at the Chinese Academy of SciencesBeijing and his colleagues tallied up all of its birdlike and dinosaurlike features, such as long robust forearms, and compared them with other species. These species included avialans, a group containing ancestors of modern birds, and deinonychosaurs, close relatives of avialans, which together are known as paravians. Avialans include dinosaurlike birds, while deinonychosaurs include birdlike dinosaurs — a blurry distinction that has led scientists to often bounce species around between the group.
When the researchers analyzed features of Xiaotingia and Archaeopteryx, the resulting family tree clustered them together. Unexpectedly, it also yanked them out of the avialan category and placed the duo with the deinonychosaurs.
New bird on the block
Now their analysis suggests the earliest known avialan is currently a pigeon-size feathered creature known as Epidexipteryx hui recently discovered in Inner Mongolia, China.
"This has a huge impact about how we view the early evolution of birds," said Witmer, who did not take part in this study. "For 150 years, scientists have tended to view their early evolution through the lens of Archaeopteryx, and how much of what they thought now needs to be re-examined?"
Still, these findings remain tentative.
"As we try to tease apart what's going on, we're left with slight differences between species, and each new find reshuffles the deck — Xiaotingia might have moved Archaeopteryx out of the birds, but the next find could move it back into birds or somewhere else," Witmer said. "That's how it should be, how science works — new evidence changes our conclusions."
Xing and his colleagues detailed their findings in the July 28 issue of the journal Nature, and Witmer wrote an accompanying commentary.

US ready to arm Philippines against rise of China


The United States has announced it is ready to provide hardware to modernise the military of the Philippines, which as vowed to "stand up to any aggressive action" amid rising tension at sea with China.

Foreign Secretary Albert del Rosario, on a visit to Washington, said the Philippines hoped to lease equipment to upgrade its aged fleet and called for the allies to revamp their relationship in light of the friction with China.
"We are determined and committed to supporting the defence of the Philippines," Secretary of State Hillary Clinton told a joint news conference when asked about the hardware wish-list from the Philippines.
Mrs Clinton said the two nations were working "to determine what are the additional assets that the Philippines needs and how we can best provide those." She said del Rosario would meet Defence Secretary Robert Gates and other Pentagon officials.
Tensions in the strategic and resource-rich South China Sea have escalated in recent weeks, with the Philippines and Vietnam alarmed at what they say are increasingly aggressive actions by Beijing in the disputed waters.
"We are concerned that recent incidents in the South China Sea could undermine peace and stability," Clinton told , urging "all sides to exercise self-restraint."
