China’s dispatch of jets over air defence zone ratchets up tension!

Analysts fear China may have miscalculated international reaction but cannot step back after raising domestic expectations,

China Asserting Airspace




The islands at the centre of the air defence zone dispute.

Tensions rose further on Thursday over China’s declaration of an air defence zone over disputed regions of the East China Sea after it sent fighter jets and an early warning aircraft to patrol the area.

The state news agency Xinhua announced the patrols after Japan, South Korea and the US had all sent military aircraft through the zone in a clear challenge to the Chinese measure. Beijing had previously responded only by saying it had monitored all the flights.

Shen Jinke, a spokesman for the Chinese air force, described Thursday’s dispatch of aircraft as “a defensive measure and in line with international common practices” in the Xinhua report.

The article said China was “on high alert and will take measures to deal with diverse air threats” to protect the security of its airspace.

Many countries have similar zones requiring aircraft approaching their territorial airspace to identify themselves, and China has said it created the area to defend its national security. But its zone is controversial because it includes the skies over islands, known as the Senkaku in Japan and Diaoyu in China, which are the subject of a long-running territorial dispute.

Japan has administrative control of the island group and the area overlaps with zones established by Japan and South Korea.

Many analysts think China is laying down a long-term marker, but did not anticipate the forceful response it has received from the US as well as Japan.

“I would be inclined to think it’s a miscalculation – but there’s a kind of strategic logic to it,” said Rory Medcalf of Australia’s Lowy Institute.

“I assume there will have been voices [internally] who wondered at the wisdom of it, but [the outcome] depends as well on how the rest of us react.”

Stephanie Kleine-Ahlbrandt, Asia-Pacific director at the US Institute of Peace, said: “They have got huge pushback and I don’t think they expected that.”

But she said the creation of its zone had its own momentum.

“The danger in the announcement is that it empowers the People’s Liberation Army, maritime agencies and netizens [internet users] to hold the government to account,” she said.

“Within the system, it empowers actors to go out and do what they think is best for their own interests … Now people are transgressing the zone, they have to make it look to the domestic audience like they are serious. They have given birth to internal pressures.”

US vice-president Joe Biden will press Chinese leaders on the issue when he visits Beijing, Tokyo and Seoul on a trip beginning this Sunday. It was initially intended to focus on economic issues but is now expected to be dominated by tensions over the East China Sea.

Earlier, Shi Yinhong, an expert on international relations at Renmin University in Beijing, warned that Japanese flights through the zone had increased the risk of escalation from confrontation to conflict.

He said: “I think China will take flexible measures towards any aeroplane that flies over the zone, and that will still be compatible with China’s declarations.

“America is not our direct enemy, and South Korea is our friend. But Japanese armed aircraft would be a different story. If they dare to come into China’s declared zone, the Chinese air force will take action.”

The state-run nationalist tabloid Global Times warned in an editorial on Thursday that China was willing to engage “in a protracted confrontation with Japan” to “beat its willpower and ambition to instigate strategic confrontation”.

Official statements have said that the zone does not target any particular country.

But tapping into populist anti-Japanese sentiment, the Global Times wrote: “All the criticism and provocation will not pose a real challenge for the newly created ADIZ. It is a fact that China has already established its ADIZ over the East China Sea.

“Maybe an imminent conflict will be waged between China and Japan. As a staunch supporter of Tokyo, Washington is expected to refrain from confronting Beijing directly in the East China Sea, at least for now. Canberra and Seoul just chimed in …

“If the US does not go too far, we will not target it in safeguarding our air defence zone. What we should do at present is to firmly counter provocative actions from Japan. Australia, having no real conflict with China now, can be ignored at the moment.”

The newspaper is known for running hawkish pieces that do not always reflect official policy, but reflect the view of some within the power elites.


In China high-speed train kills four rail workers!

Beijing: A Chinese high-speed train killed four maintenance workers after a communication failure, state media reported today, the latest fatal incident on the country’s flagship rail network.

The D28 train was at least 11 minutes behind schedule when it hit five railway personnel maintaining and cleaning the track during what was supposed to be their “working hour window”, the 21st Century Business Herald said.

Four of the staffers, all under 30 and two of them new university graduates, were killed and one injured, said the report, which cited an internal railway circular.

China’s high-speed rail network is the largest in the world, and seen by Beijing as a symbol of the country’s advance.

But the expansion — which has cost hundreds of billions of dollars — has seen a series of scandals and widespread allegations of corruption, with accusations that safety has been compromised for speed.

The incident, between Taian and Panjin North in the northeastern province of Liaoning on Friday, was the latest fatal accident on the network.

At least 40 people were killed in a high-speed train crash near Wenzhou in Zhejiang province in July 2011.

Ex-railway minister Liu Zhijun, who campaigned for and oversaw the expansion of the high-speed network, was given a suspended death sentence in July for taking USD 10.6 million in bribes.

US warplanes flyover of disputed area defy Chinese air defence rules with B-52


Two US B-52 bombers flew over a disputed area of the East China sea without notifying Beijing.

US warplanes have directly challenged China’s claims of an expanding territorial air defense zone, flying dramatically and without incident on Monday over a disputed island chain.

The incursion comes on the heels of a scathing statement over the weekend by defense secretary Chuck Hagel rejecting the expansion of the Chinese air defense zone into the East China sea as a provocative threat to regional stability.

But the Pentagon insisted Tuesday that the overflight was not a reaction to the Chinese declaration.

Lieutenant colonel Tom Crosson, a Defense Department spokesman, said the planes were not armed and flew “as part of a long-planned training sortie”. The Chinese did not in any way attempt to challenge the planes’ flight, Crosson said, nor did the pilots announce themselves to any Chinese authorities.

Crosson said the Pentagon had yet to receive a message from China in response to the overflight.

“You’ll probably hear a lot of boisterous statements out of China that it’s a provocation,” said Nick Szechenyi of the Center for Strategic and International Studies.

While US navy ships frequently traverse the Taiwan Strait, it is extremely rare for the US military to issue a blatant show of force near Chinese-claimed territory. For years, the Pentagon has argued unsuccessfully for a direct military-to-military communications channel to prevent potentially catastrophic misunderstandings in the region.

As first reported by the Wall Street Journal, the US air force flew what it said were a pair of B-52 bombers from an airbase on Guam over what China calls the Diaoyu Islands and what Japan calls the Senkaku Islands. Both nations claim the chain, as well as oil and gas fields nearby, and both nations have harassed each other’s nationals, at sea and in the air, over perceived disruptions in the status quo.

But China’s Saturday declaration that it had expanded its air defense zone into the East China sea – with its attendant implication that China will shoot down unauthorized aircraft – was met with scathing condemnation from Hagel.

“We view this development as a destabilizing attempt to alter the status quo in the region,” Hagel said in a statement over the weekend. “This unilateral action increases the risk of misunderstanding and miscalculations.”

Hagel warned China that US military operations in the western Pacific would “not in any way change”. The flight of the air force planes, even if they were on a long-planned training mission, is the first clear demonstration of Hagel’s declaration.

Crosson did not describe the training mission beyond saying the two planes flew from Guam and back.

“This was not a reaction” to China’s expansion of its air defense zone, Crosson said.

It is unclear whether China will view it that way. The Chinese foreign ministry on Monday condemned Hagel’s remarks as “irresponsible”.

The rise of China as a regional military heavyweight has long preoccupied the Pentagon, which has routinely stated sees China as a potential partner. The former chairman of the Joint Chiefs of Staff, Admiral Mike Mullen, implored China to no avail to establish a direct communications channel between the two militaries to ward off potential misunderstandings.

China is expected to participate in a major Pacific wargame alongside the US navy and its regional allies next year. China said in March that it would take part in the Rim of the Pacific exercises for the first time, seemingly auguring closer US-Chinese military ties.

“Engagement with China is very important to assure China its rise is welcome, but on the flip side, you have to dissuade China from taking potentially destabilizing actions.”

A comparable US military challenge to Chinese power has not happened for nearly two decades

Szechenyi, of the Center for Strategic and International Studies, looked back to the 1996 “Taiwan Strait Crisis”, in which the US sent two aircraft carriers to the Taiwan Strait following a series of Chinese military escalations, as a recent analogue.

“The US has stated repeatedly that it would not accept any unilateral actions that attempted to alter the status quo and this was interpreted very quickly a such an act,” he said.

China sends carrier to South China Sea for training amid maritime disputes!

BEIJING (Reuters) – China sent its sole aircraft carrier on a training mission into the South China Sea on Tuesday amid maritime disputes with some neighbours and tension over its plan to set up an airspace defence zone in waters disputed with Japan.

The Liaoning, bought used from Ukraine and refurbished in China, has conducted more than 100 exercises and experiments since it was commissioned last year but this is the first time it has been sent to the South China Sea.

Though considered decades behind U.S. technology, the Liaoning represents the Chinese navy’s blue-water ambitions and has been the focus of a campaign to stir patriotism.

The Liaoning left port from the northern city of Qingdao accompanied by two destroyers and two frigates, the Chinese navy said on an official news website (

While there, it will carry out “scientific research, tests and military drills”, the report said.

“This is the first time since the Liaoning entered service that it has carried out long-term drills on the high seas,” it added.

It did not specify exactly what training would be done, only noting that previous exercises involving aircraft landing and taking off had gone well and laid a firm foundation for future tests.

Previously reported training exercises have mostly been in the Yellow Sea.

China’s Defence Ministry said on Monday that it had lodged formal protests with the U.S. and Japanese embassies after both countries criticised a Chinese plan to impose new rules on airspace over disputed waters in the East China Sea.

China also claims almost the entire oil- and gas-rich South China Sea, overlapping claims from Taiwan, Malaysia, Brunei, the Philippines and Vietnam.

That dispute is one of the region’s biggest flashpoints amid China’s military build-up and the U.S. strategic “pivot” back to Asia signalled by the Obama administration in 2011.

China’s navy said the mission was routine, adding that the Liaoning was still in a testing phase.

“This test visit to the South China Sea is part of normal arrangements for testing and training for the Liaoning,” it added.

In China oil explosion Arrested!

Nine were detained after Sinopec pipeline leak and blast in Qingdao city killed near by 55 people and many more were injured,


An overturned car and buckled pavement after the Qingdao oil pipeline explosion.

Police have detained seven employees of China‘s largest oil refiner, Sinopec, following an oil pipeline blast that ripped through residential and commercial roads in an eastern port city, killing at least 55 people.

A statement late on Monday from the local authority that overseas Qingdao city’s economic and technological development zone said two of its employees were also in police custody.

Three more bodies were found on the scene Monday, raising the death toll to 55.

Friday’s blast injured more than 160 people and left nine others missing.

The accident has been the deadliest involving state-owned company Sinopec. The pipeline ruptured and leaked for about 15 minutes onto a street and into the sea. Hours later the oil caught fire and exploded in two locations.
