Very weak indeed! China needs an aggressive military general instead of Xi.

Compared to Hu and Jiang, Xi is miles ahead ... China does not need an aggressive military general like Chiang Kai-Shek if that's what you mean. Xi is already a very good mixture when it comes to asserting Chinese influence

WTF, these westerners complain to WTO that China set restriction of selling rare earth but they block rhenium export to China...and China did nothing.

That's why China has been restricting its other rare earth metals ... because of unfair restrictions such as Rhenium. Basically, it's a tit for tat approach ...

WTF, these westerners complain to WTO that China set restriction of selling rare earth but they block rhenium export to China...and China did nothing.

Now China has unified it's rare earth sector to ensure environmental protection and price stability.

The Western shills need to obey to the laws.

China plans to catch up with advanced aero engine producers in 20 years

“China plans to catch up with the advanced aero engine producers in 20 years,” said Cao Jianguo, chairman of the Aero Engine Cooperation of China (AECC).

Only five countries in the world – the five permanent members of the United Nations Security Council - are able to produce aero engines, Cao noted. Though being in this group, China is still hindered by out-of-date technologies.

With the development of aero engines and improved research cycle time, it is possible for China to accomplish this mission, Cao added.

It takes more than 20 years to develop a new-generation aero engine, which is the world’s most complicated machinery system, and which combines multiple disciplines.

In addition, the technical barriers also require astronomical amounts of capital. A medium-large sized aero engine costs around $2-3 billion for research and development, and the figure doubles when it comes to more advanced machines.

“Design capability is China’s biggest weakness,” remarked Yin Zeyong, a member of the Chinese Academy of Engineering and head of AECC’s science and technology commission. Design, tests, and trial flights all contribute to the time it takes to develop aero engines, but enhancing design capability is the only way to smooth the development, Yin said.

Besides, China now lacks a standardized code system, which forms the basis of the most advanced aero engine producers, noted Wang Yingjie, director of the management innovation department of the AECC. “We still have a long way to go in this regard,” he stressed.

However, China’s state-run system is a key factor that drives the development of the country’s aero engines. “Related enterprises are sparing no efforts to support us,” said Luo Ronghuai, vice chairman of the AECC. “They are supporting us even at their own losses when we need specific steels in very limited amount,” he added.

China will establish a development and research system for aero engines before 2020. According to Wang, the AECC is currently planning on a comprehensive operation and management system covering four major aspects: research, manufacture, supplier management, and service assurance. In addition, a self-developed standardized code system for research and development will be completed.

Must read this article posted by @GiantPanda on 2017-09-10 at the COMAC C919 thread:

"C919 jumbo jet expected to be powered by homemade engine: expert"

• China's domestically developed jumbo jet C919 is expected to be equipped with homemade engines "soon"
• Domestically made Changjiang-1000 engine (CJ-1000) that may be used to power the C919 is under development and will replace imported foreign engines in future on the jet, according to Cao Chunxiao, an academician with the Chinese Academy of Sciences and a researcher with Aero Engine Corporation of China Beijing Institute of Aeronautical Materials, said on Saturday (09 SEP).
• Nearly 23 percent of the CJ-1000 engine will probably be titanium alloy, which has higher density than iron and will help reduce the weight of the jet, Cao said during the 2017 China's Top 500 Enterprises Summit Forum on Saturday in Jiangxi, thepaper.cn reported.
• "The first Changjiang-1000 (CJ-1000) engine is expected to be completed by the end of 2017 and a series of intensive tests are planned when it is mounted on an airplane," Feng Jinzhang, general manager at AECC Commercial Aircraft Engines Co, said at a forum on August 26.
• The CJ-1000 is designed for C919, but is expected to power either Boeing 737 or Airbus 320 or a similar newly built aircraft in the world market by 2025, Wang said.

No ... that's Russia. Ukraine doesn't exactly produce AL-31 turbofans ...

Chinese aero-engine manufacturer shows high-end models at expo

BEIJING, Sept. 11 (Xinhua) -- Aero Engine Corporation of China (AECC), the country's leading state-owned aircraft engine manufacturer, will show its high-end products at the upcoming Aviation Expo China 2017.

The company will exhibit its major achievements in promoting integrated military and civilian development at the expo, which will be held in Beijing from Sept. 19 to 22, according to the AECC.

It will exhibit one aircraft engine, two gas turbines, as well as two patented technologies of graphene material and high precision aluminum alloy.

The WZ16, a model of turboshaft engine, jointly developed by the AECC and French aviation giant of Safran, will also be displayed.

The WZ16 can be fitted to a seven-to-eight tonne helicopter, or 13-tonne triple-engine helicopter. On Dec. 20 last year, it completed a successful maiden flight on the AC352, China's first seven-tonne multi-purpose twin-engine helicopter.

Meanwhile, the AECC will exhibit its QD70 gas turbine and 100KW small-sized gas turbine, which can operate on a variety of fuels for multiple uses.

Aircraft and turbo engines are a representative industry for China's industrial development.

The state-owned AECC was set up on Aug. 28, 2016, with a target of accelerating independent research, development and manufacturing of aircraft engines and gas turbines.

Founded in 1984, China Aviation Expo was China's first professional aviation expo. This year it has attracted more than 300 exhibitors from 14 countries and regions.

So can Japan.

Well, the article doesn't explicitly mention it but they are implicitly referring to high thrust military engines not just any random aero engine that a lot countries can probably make if they have the will to do so. When it comes to the very high-thrust turbofans which is the main focus area, only 3 countries currently make military turbofans which are well above 100kN which are the US, Russia and China.
My point is if you lower the standard enough then many other countries outside the traditional players can be put on the list though that's not the point of the article.
Of course we also have to note the differences between civil and military engine development effort.

Latest fighter jets to use domestically made engines by 2022: experts

China's latest fighter jets will be powered by domestically made engines by 2022, experts said, as a television crew was given a glimpse of a J-11B fighter's radar system and engine.

"More Chinese fighting jets, including the J-10, J11, J-20 and J-31, will be powered by homegrown engines. China's new generation of military jets will all be powered by domestically-made engines within five years," Xu Guangyu, a senior adviser to the China Arms Control and Disarmament Association, told the Global Times.

The J-11B is powered by two domestic-made engines, a China Central Television (CCTV) reporter said, who gained access to a secret warehouse of the Shenyang Aircraft Corporation, a major fighter jet producer located in Northeast China's Shenyang Province. CCTV aired a report on the jet on Tuesday.

"The domestically made engine WS-10C on the J-11B is quite competitive to the previous Russian-made AL31 engine," Xu Yongling, an air force expert at the Chinese Society of Aeronautics and Astronautics (CSAA), told the Global Times.

Newly produced J-11B jets will be powered by the WS-10C, but engines on the current 120 J-11Bs won't be totally replaced due to the high cost, Xu Yongling said.

"China still lags behind in turbofan engines, especially engines that feature domestic single-crystal turbine blades made from metal rhenium," Xu Guangyu explained.

Most of the technology of single-crystal turbine blades is in the hands of State companies, Wang Yanan, chief editor of the Aerospace Knowledge magazine, previously told the Global Times. The Sichuan Province-based Chengdu Aerospace Superalloy Technology Company became China's first company to mass produce single-crystal turbine blades, CCTV had earlier reported.

The participation of private firms in the aviation industry would make production more efficient, Wang said.

Xu Youngling said the military aircraft engine industry is monopolized by State-owned companies, and will still take some time before more private companies enter this high-end industry.

"The domestic engines will be gradually tested on more fighters, Xu Guangyu stressed, adding that it would be strategically beneficial to the army since most fighter jets are powered by Western-made engines.

WS-10C ??????

Yeah, I'm not sure why they said that. Maybe that is the real designation. I'm pretty sure that Mr. Xu Yongling has more knowledge about Chinese engines than any poster or "Big Shrimp" here though! Very interesting revelation if accurate ....

By the way if he means "Latest fighter jets to use domestically made engines by 2022" and connects this with the J-11B-production & WS-10C, I have daubs that then a WS-15 will be ready soon.
