China dominates South Korea in almost every high-technology field (Score 12-0 in China's favor).
Adding China's Huawei telecommunications technology to the list against non-existent South Korean technology.
1. China won the Nobel Prize in Medicine and the Lasker Award (ie. American Nobel Prize) for Artemisinin. China's Artemisin saves millions of lives each year. South Korea has done nothing notable in the field of medicine.
2. China built an indigenous DFH-4 communications satellite with 54 transponders. South Korea has no such capability.
3. China built an indigenous atomic clock in 1972. South Korea imported foreign know-how in 2008 to build an atomic clock.
4. China built an indigenous YF-73 cryogenic rocket engine in 1984. South Korea purchased a Russian cryogenic rocket engine in 2009.
5. China built an indigenous Beidou/GPS satellite with an accuracy of 0.1 meter (see Nature citation earlier). South Korea has no idea how to build a GPS satellite.
6. China has built many turbofan engines, including the high-bypass WS-20. South Korea has never built its own turbofan engine. South Korea is like a Mexican maquiladora screwdriver-plant. South Korea assembles foreign GE F404 engine kits.
7. China built the indigenous "China Star" high-speed train with a top speed of 300 kilometers per hour. South Korea imported French high-speed trains in 2004.
8. China's indigenous Jiaolong manned submersible set a world-record dive of 22,844 feet. South Korea doesn't know how to build a manned submersible.
9. China builds the One Teraflop Sunway BlueLight supercomputer. South Korea doesn't know how to build a supercomputer. South Korea imports foreign supercomputer technology from America's Cray supercomputer.
10. China's fast-breeder research nuclear reactor was connected to the electric grid in 2011. This means the Chinese fast-breeder reactor is operational. South Korea doesn't know how to build a fast-breeder nuclear reactor.
11. China is a world leader in superconductors. China made two important discoveries (see Nature citations below). Firstly, China broke the high-temperature record for a superconductor at 48 Kelvin for iron-selenide superconductors. This brings the ultimate goal of a room-temperature superconductor one step closer. Secondly, China proved that a superconductor only has to be one atom thick to function. Prior to China's discovery, everyone believed that a material needed a minimum of two-atom thickness to superconduct.
South Korea has made no discernible impact in the field of superconductors.
12. China's Huawei is a world leader in telecommunications equipment. China's Huawei and Europe's Ericsson are number one and two in almost every important telecom category. South Korea has no real presence in telecommunications equipment.
The score is China (12) to South Korea (0). This is complete domination by Chinese high-technology over non-existent South Korean technology.

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

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."
