Name one single high end product that Chinese manufacturing sector has developed on its own..
1. China develops its own high technology. General Electric and Siemens most certainly did not provide China with their patented technology to manufacture rotors for 1,000MW turbines.
2. Huawei is a world leader in communications technology.
3. China is a world leader in machine tool technology.
4. China is a world leader in cloning technology.
I could go on, but I will stop at four examples. I don't want to look like I'm bragging.

Rotor for 1,000MW Ultra-supercritical Steam Turbine
November 9, 2011
China has already manufactured a 12% Chromium high-quality forged rotor for an 1,000MW USC (ultra-supercritical) steam turbine under high pressure.
China’s strategy to meet its greenhouse gas commitment is to continue full steam ahead by converting its coal-fired power plant fleet from a conventional one to an ultra-supercritical one — a move that will decrease its energy intensity from coal-generated power by more than 20 percent.
A coal-fired power plant operates by boiling water to create a high-pressure steam that drives a turbine which produces electricity by moving an electrical wire through a magnetic field.
A conventional (or subcritical) plant typically operates at temperatures up to 1,050 degrees Fahrenheit and has an efficiency of between 33 and 39 percent. Operating a plant at higher temperatures and pressures can increase its efficiency, potentially lowering emissions of carbon dioxide (CO2) in the process.
A so-called supercritical plant operates at sufficiently high pressures and temperatures (between 1,000 and 1,075 degrees Fahrenheit) such that the water and steam become indistinguishable (the critical point of a liquid), allowing efficiency rates to reach 42 percent. An ultra-supercritical plant operates at temperatures of 1,075 degrees Fahrenheit and above and can achieve efficiencies of more than 42 percent.
China has jumped into the ultra-supercritical game with both feet. It is busy building supercritical and ultra-supercritical power plants at an astonishing rate — a whole lot faster, by the way, than we are here in the United States. And China’s ultra-supercritical power plant that went online in Yuhuan in 2006 reportedly holds the record as “the world’s cleanest, most efficient and most advanced ultra-supercritical units” with an efficiency of 46 percent.
Until now, the key high temperature equipment for supercritical and ultra-supercritical power units were mainly imported from foreign countries. China currently requires our national enterprises to domestically manufacture the key high temperature equipment. For making seamless tubes and large pipes, Chinese enterprises will be equipped with more 35MN, 60MN and one 350MN extrusion machines in the near future.
Large-scale castings for 1,000MW USC steam turbine already can be made in China. Large-scale forging have been also trial-produced. High-purity low alloy steel forging for low pressure rotor and 12% Cr high-quality forged rotor for 1,000MW USC steam turbine high pressure rotor are made in China."

Huawei Unveils Industry’s First Giga DSL Prototype
Huawei Smart AX M5300. The Smart AX MA5300 platform has been instrumental to Huawei's success in the global DSLAM (digital subscriber line access multiplexer) market, but the MA5600 series, designed to support more bandwidth-intensive services such as triple/quad play, is the company's flagship DSLAM.

Huawei Unveils Industry’s First Giga DSL Prototype
Mariah Lawson on 12 19, 2011
Can Achieve Access Rate of One Gbps per Twisted Pair
Shenzhen, China,
Huawei, a leading global information and communications technology (ICT) provider, today announced that it successfully launched the industry’s first Giga DSL (Digital Subscriber line) prototype. The Giga DSL system employs time division duplex (TDD) to achieve a total upstream and downstream rate of 1,000 Mb/s over a single twisted pair.
In order to address obstacles related to limited bandwidth of FTTB (Fiber to the Building)/FTTC(Fiber to the Curb) and difficulty in deploying FTTH (Fiber to the Home) drop cables – so that users can enjoy bandwidth-hungry services such as IPTV and HDTV – optical fiber access points need to be located closer to users. While, 100 Mbp/s-plus ultra-broadband access can be made available relatively quickly by utilizing legacy copper line resources, providing 1,000 Mbp/s bandwidth within 100 meters of twisted pairs using DSL technology is more complex.
By using low-power spectral density in-signal transmission, Huawei’s Giga DSL prototype reduces radiation interference and power consumption, and provides a total upstream and downstream rate of one Gb/s within 100 meters, and 500 Mb/s-plus within 200 meters – making it a cost-effective option for telecom operators building ultra-broadband access networks.
Giga DSL is a next-generation access technology solution that's growing quickly. In 2011, ITU-T set up a G.fast project team dedicated to formulating new standards for ultra-speed access at short distances, the aim being to achieve 500 Mb/s access rate per twisted pair within 100 meters. Huawei has actively participated in the work of the team and has become a major technical contributor, having recently worked to incorporate TDD-OFDM (Orthogonal Frequency Division Multiplexing) as a G.fast modulation mode.
Dr. Long Guozhu, Huawei’s Principal Expert of DSL technology, said, “Huawei has taken the lead in developing a Giga DSL prototype because of our rich capabilities and industry-leading technical strengths in access networks. It was inevitable that spectrum expansion would help us improve the rate of a twisted pair at a short distance, but after the spectrum is expanded, a technical issue appears: how to design the high-speed physical layer and high-frequency analog front end (AFE). To tackle this issue, Huawei’s FBB Innovation Lab used the core solution TDD-OFDM, which simplifies the physical-layer architecture and the AFE design, while at the same time makes it possible to be downward compatible with traditional ADSL/VDSL2 technologies.”
Huawei also recently announced the successful development of the world’s first node level vectoring (NLV) prototype. Huawei’s vectoring product provides 100 Mbps access over a single twisted pair in FTTC/FTTB, and has been tested and commercially trialed with many leading telecom operators. This, along with the company’s latest prototype, Giga DSL, signifies that DSL technology still has great potential to meet the requirements of broadband users for ultra-high-speed access in the future.
Huawei’s advances within Giga DSL will enhance the capabilities of the company’s SingleFAN broadband access solution. Its SingleFAN solution and related offerings are now servicing over one third of the world’s broadband users with ultra-broadband access services."

"China gets success in cloning world's first rabbit
Parul G | Jul 24 2007
After research of more than three decades in cloning and producing the first cloned animal, a goat in 2000, China has once again been successful in cloning world’s first rabbit. The Chinese scientists have produced the cloned female rabbit biologically, using the somatic cells of a rabbit fetus.
Dr. Li Shangang who conducted the experiment of rabbit cloning is a researcher at the National Center for Molecular Genetics and Animal Breeding of the Beijing Institute of Animal Sciences.
Dr. Li and his team chose the back skin cells of a 20-day old rabbit embryo. They cultured these cells into fibroblast cell lines. Then these fibroblast cells (donor cells) were fused with an enucleated rabbit’s oocyte (immature egg cell of animal ovary) through electric pulse. Thus cloned embroys were produced which were later transferred into the rabbit’s oviduct. The female clone rabbit was born after a month-long normal pregnancy on February 12 and had weighed 60 grams at birth. Now the rabbit is doing well and is at an animal center in Shanghai.
The first animal to be cloned using somatic cells was the sheep - Dolly in 1996. Since then many other animals as mice, cattle and ###### have been cloned by scientists.
In 2002, French scientists too had claimed to produce the world’s first cloned rabbit but that was done by using cells from an adult female rabbit.
However, the Chinese rabbit is the world’s first clone rabbit that has used “fibroblast” cells from a fetal rabbit.
On the achievement, Wang Hongguang, director of the China Center for Biotechnology Development affiliated to the Ministry of Science and Technology said:
Chinese cloning research has reached a global advanced level. We can reproduce almost all the cloning results in top-class laboratories around the world. However, we are lacking in original creations such as the newly cloned rabbit.
Rabbits are considered significant research tools because of their shorter gestation period than other big mammals such as sheep or cows.
Malaysia has also turned to cloning and is in efforts to clone some of its threatened leatherback turtles to save them from extinction.

"China's Liberation Daily reports today that the world's first transgenic-cloned rabbit is now three months old and living happily in Shanghai. The rabbit was cloned from the skin cells of a 20-day-old embryo, which were then implanted into the oviduct of a female rabbit."
