Trump reviews 'Made in America' products at the White House
China Daily | Updated: 2018-07-25 07:51


WASHINGTON - Checking out a speedboat, a fighter jet and a giant industrial magnet parked on the White House driveway, US President Donald Trump showcased an array of "Made in America" products on Monday as his administration pushes back aggressively against critics who say his punishing tariffs on imported goods threaten to harm the US economy.

Trump's event with a smorgasbord of US goods came at the start of a week in which trade discussions are expected to dominate, including talks with European officials and a trip to the state of Illinois in which the president is planning to visit a community helped along by his steel tariffs.

Trump has vowed to force international trading partners to bend to his will as he seeks to renegotiate a series of trade deals he has long argued hurt US workers. But as he deepens US involvement in trade fights, it raises questions on whether consumers will feel the pain of retaliatory tariffs - and whether the president will incur a political price for his nationalistic trade policies in the 2018 midterm elections. "Our leaders in Washington did nothing, they did nothing. They let our factories leave, they let our people lose their jobs," Trump said at the White House. "That's not free trade, that's fool's trade, that's stupid trade and we don't do that kind of trade anymore."

Trump noted that he would be meeting on Wednesday with European officials, including European Commission President Jean-Claude Juncker. The US and European allies have been at odds over the president's tariffs on steel imports and are meeting as the dispute threatens to spread to the lucrative automobile business.

"Maybe we can work something out," he said.

Victimization

Trump has already put taxes on imported steel and aluminum, saying they pose a threat to US national security, an argument that enrages staunch US allies such as the European Union and Canada.

He's threatening to use the national security justification again to slap tariffs on imported cars, trucks and auto parts, potentially targeting imports that last year totaled $335 billion.

And he's already imposed tariffs on $34 billion in Chinese imports in a separate dispute over Beijing's high-tech industrial policies. He has threatened to ratchet that up past $500 billion.

"He likes tariffs," said William Reinsch, a former US trade official under President Bill Clinton now at the Center for Strategic and International Studies. "His preferred remedy is always tariffs, whether it makes any sense or not.

"It's a policy of victimization: 'Other people have been taking advantage of the United States for years ... Now they have to pay,'" Reinsch said, echoing the president's argument.

Trade analysts say the United States has not pursued such aggressive trade policies in decades.

"I can't think of another time when you had as many battles and particularly as many battles with no resolution in sight," said Edward Alden, senior fellow at the Council on Foreign Relations.

Why China’s first stealth fighter was rushed into service with inferior engines
18 Jun 2018

China rushed its first advanced stealth fighter jet into service ahead of schedule last year, using stopgap engines, in the face of rising security challenges in the region, the South China Morning Post has learned.

But that means its capabilities will be severely limited, affecting its manoeuvrability and fuel efficiency as well as its stealthiness at supersonic speeds.

Without saying how many were in operation, the People’s Liberation Army Air Force confirmed on Friday that the J-20, the country’s fifth-generation fighter, had entered combat service, meaning it was combat-ready.

However, the aircraft was equipped with inferior engines designed for earlier warplanes when it first joined the air force in March last year because “critical problems” with its tailor-made WS-15 engine, exposed by an accident in 2015, had not been fixed, two independent military sources told the Post.


“The WS-15 engine designed for the J-20 exploded during a ground running test in 2015,” one source said, adding that no one was injured in the accident.

“The explosion indicated the WS-15 is not reliable, and so far there is no fundamental solution to overcome such a problem … that’s why the J-20 is using WS-10B engines now.”

The WS-10B is a modified version of the WS-10 Taihang engine, which was designed for the country’s fourth-generation J-10 and J-11 fighters.

The explosion was confirmed by another source close to the military, who said the reasons it happened were complicated, with one being the quality control of its single-crystal turbine blades, the key component for such a powerful turbofan engine.

The new-generation, single-crystal turbine blades designed for the WS-15 were supposed to be able to cope with the increased mechanical loads caused by significantly higher rotational speeds and extremely high temperatures.

Former Aviation Industry Corporation of China (AVIC) chairman Lin Zuoming told state media last year that China’s third-generation single-crystal turbine blades could withstand temperatures of up to 3,632 degrees Fahrenheit (2,000 degrees Celsius) in WS-10 engines, extending the engine’s lifespan from 800 hours to 1,500 hours when compared with those using the previous generation of turbine blade.

However, the thrust-to-weight ratio of the original WS-10 engine was only 7.5, while that of the WS-10B tops out at about nine. The thrust-to-weight ratio of the all-direction, vector turbofan WS-15 Emei engine is more than 10 – one of the basic requirements for giving the J-20 “supercruise” ability.

Supercruise allows stealth fighters like the US’ F-22 Raptor to fly at supersonic speeds without using afterburners, making them harder to detect. The F-22 is powered by the world’s most advanced jet engine, the Pratt & Whitney F119.

But achieving supercruise would require the single-crystal turbine blades of the WS-15 engine to cope with temperatures even more extreme than those handled by the WS-10.



“Chinese technicians are able to produce cutting-edge-quality single-crystal turbine blades when concentrating on a specific single item,” the second military source said. “But they’ve still failed to turn the advanced technology into a standard product for mass production. It’s a bottleneck problem that needs more time to overcome after countless experiments and tests, based on Western experiences.”

“Using the WS-10B engines is just a temporary, expedient stage of the J-20’s engine development … in the future, the aircraft may use another new engine, the improved performance engine (IPE) version of the WS-10, the WS-10 IPE, until the development of the WS-15 is successful,” the first source said.

“It’s so embarrassing to change engines for such an important aircraft project several times … just because of the unreliability of the current WS-15 engines. It is the long-standing core problem among home-grown aircraft.”

It is at least the third time the J-20 has changed engines. The aircraft’s maiden flight was powered by two Russian AL-31 engines, which are less capable than China’s WS-10B.

Russia has refused to export its most advanced engines to China because they are the core technology of its aviation industry. That prompted China to develop an indigenous alternative, the WS-15, as part of its drive towards producing one of the world’s most advanced combat aircraft.

Beijing has stepped up the development of sophisticated jet engines since the turn of the century, with at least 150 billion yuan (US$23.7 billion) invested between 2010 and 2015, military insiders told the Post in 2016.

State-owned Aero Engine, a company formed in August 2016 through the merger of 24 AVIC subsidiaries with about 10,000 employees, has led China’s development and production of aircraft engines and gas turbines in recent years. One of the former AVIC subsidiaries, Shenyang Aeroengine Research Institute, developed the WS-10 and WS-15.



China Central Television boasted last year that the performance of the WS-15 had matched that of the F119, with a documentary aired in May claiming the WS-15 engines would be widely used in the J-20 by 2020.

That would make China the third country to have a fifth-generation fighter – after the US and Russia. Justin Bronk, a research fellow specialising in combat air power at the Royal United Services Institute, told Business Insider the design of the J-20 gave it “longer range, more internal fuel capacity, and larger internal weapons capability” than its US counterparts, the F-22 and F-35, and that meant it presented a real threat to US forces in the Pacific.

However, military analysts said it was too early for such prognostications because the underdeveloped WS-15 engine was not yet as sophisticated as the F119, which had a lifespan of more than 4,000 hours.

Chinese military buffs build replica J-20 stealth fighter

The prototype of Russia’s first fifth-generation fighter jet, the Su-57, took to the air for the first time in January 2010 but its maiden flight powered by the new Izdelie 30 engine, which was specially designed for it, only took place last month. The new engine will enable the Su-57 to achieve supercruise speed and fly consistently at 1,242mph (2,000km/h), but it still faces many tests, with the Russia Beyond website saying it would not be mounted on the Su-57 before 2019 or 2020.

China’s WS-15 project started in the 1990s, with the first prototype delivered in 2004 and the first successful ground-running test staged in 2015, Antony Wong Dong, a Macau-based military observer, said.

“China took 11 years to test the WS-15 after its prototype was created,” Wong said. “It’s very normal to take three to eight years for further development.

“And it’s still a significant achievement for China to develop the WS-10B as a stopgap for the J-20. China’s advanced aircraft engine technology foundation is very weak because its research and development started several decades later than its Western counterparts.”



America’s Pratt & Whitney and General Electric spent more than 12 years developing prototypes of the F119 engine in the 1980s, followed by another 14 years of testing after the engine’s maiden flight, fitted to an F-22, in September 1997.

The US also began developing the F-35, a single-seat, single-engine, all-weather stealth multirole fighter in the 1990s, with the first squadron – using Pratt & Whitney F135 engines, a derivative of the F119, joining its air force in 2016.

The US has started deploying F-35s at its military bases in the Asia-Pacific region, with 12 arriving at the Kadena Air Base in Japan in November. South Korea has said it plans to take delivery of 40 F-35s this year.

From stealth fighters to ballistic missiles, China shows the world its weapons of war

Earlier reports said Japan’s Maritime Self-Defence Force was also considering buying the F-35B “jump jet” version for its two new 25,000 tonne, flat-topped Izumo-class helicopter carriers. That pushed Beijing to put the J-20 into service as early as possible, military sources said.

Andrei Chang, e***or-in-chief of Canadian-based Kanwa Asian Defence, said the J-20 might need at least eight years to improve its engine performance, but it was still the PLA Air Force’s most capable combat aircraft when it came to countering America’s F-22.

“The J-20 is more advanced than China’s fourth-generation fighters because of its stealthiness,” he wrote in the latest e***ion of the magazine, adding that it could also carry a greater quantity of more advanced air-to-air missiles.



Chang said he did not expect China to put the J-20 into mass production until the WS-15 project was wrapped up, but that training of J-20 pilots had been going on for a while. He said the PLA Air Force had deployed J-20s to the Dingxin Test and Training Base in Gansu province, where they and other warplanes had been used to study counter measures against the F-22 and F-35.

Hong Kong-based military commentator Liang Guoliang said there was a “very urgent” need for China to develop a carrier-based stealth fighter based on the J-20 because of the regional security environment was becoming more challenging.

America’s F-35 fighter jet vs China’s J-20: which is better, cheaper, stealthier?

“The US F-35B is much more powerful than China’s current carrier-based fighter, the J-15,” Liang said. “In case there is a war, the fighting capability of a Japanese Izumo helicopter carrier could come up to that of a Chinese aircraft carrier if each ship is equipped with five to six F-35Bs, with each one the equal of 10 J-15s.”

But, he cautioned, it would take at least a decade to turn a land-based fighter jet like the J-20 into a carrier-based aircraft because of the extensive modifications required, adding that the US had been developing carrier-based aircraft since the 1930s, while China had just started doing so this century.

China’s carrier-based J-15 is based on the Russian Su-33, a variant of the fourth-generation Su-27 fighter.

“China should hurry up; the central leadership should make a decision as soon as possible,” Liang said.

Nguồn dìm TQ là 1 tờ báo HK xuất bản từ tháng 2, viết bởi 1 con nhà báo HK Minnie Chan cùng với 1 số thằng chuyên gia ko biết ở đâu chui ra, ko tên tuổi, ko hề chuyên về quân sự, mang tính anti TQ cuồng tín, trong bài có nhiều đoạn so sánh TQ vs cả 1 nền công nghiệp phương tây đi trước, trong khi phương tây (Western) là chỉ chung lấp liếm, gồm cả các nước như Hà Lan, Đan Mạch vốn ko có trình độ chế tạo máy bay hay động cơ. Hài hước hơn là chuyên gia vô danh còn thủ dâm 1 F35B = 10 J15, trong khi F35 bản thân bị chính chuyên gia Mỹ trắng có tên tuổi, cha đẻ F16 tuyên bốkhông chiến thua cả Mig 21 (thực tế không chiến còn thua cả F16 nếu 1 vs 1)

Nếu F35B tốt vậy, sao Nhật còn chưa mua trang bị cho xà lang chở trực thăng ? Nhật nó cũng ko thủ dâm như bọn chuyên gia HK (thực chất là bọn Hán gian, tư tưởng chống cộng, thích trở lại thời bị Anh đô hộ)

Facebook bị rút giấy phép ở Trung Quốc sau một ngày được cấp
Thông tin Facebook thành lập chi nhánh ở Trung Quốc vừa gây xôn xao thì hôm nay, cánh cửa đã tiếp tục đóng lại với mạng xã hội này.
Facebook mở công ty con ở Trung Quốc

Trong khoảng vài giờ ngày 25/7, một cơ sở dữ liệu của chính phủ Trung Quốc cho thấy Facebook được phê duyệt để mở một công ty con tại thành phố Hàng Châu, tỉnh Chiết Giang. Trả lời báo chí Mỹ, Facebook cho biết sẽ thành lập một trung tâm sáng tạo ở quốc gia đông dân nhất thế giới "nhằm hỗ trợ các nhà phát triển, nhà sáng tạo và startup". Họ đã xây dựng những trung tâm tương tự tại Pháp, Brazil, Ấn Độ và Hàn Quốc.

Tuy nhiên, thành công của Facebook ở Trung Quốc vô cùng ngắn ngủi. Thông tin cấp phép đã biến mất trên hệ thống. BáoNew York Times trích nguồn tin nội bộ cho biết giấy phép bị rút lại do bất đồng giữa các quan chức của tỉnh Chiết Giang và cơ quan quản lý Internet Trung Quốc (Cyberspace Administration of China). Cơ quan này tỏ ra tức giận vì đã không được tham khảo ý kiến.

Hôm qua, việc Facebook có cơ hội thành lập công ty con mang tên Facebook Technology ở Trung Quốc được đánh giá là một bước ngoặt rất lớn với mạng xã hội này bởi trong suốt gần một thập kỷ qua, họ vẫn đang bị chặn với đa số người dân ở đây.


Năm 2016, ông chủ Facebook khoe ảnh chạy bộ tại Bắc Kinh như muốn thể hiện sự quan tâm của ông với Trung Quốc.

Tình huống hy hữu trên cho thấy những thách thức lớn như thế nào khi các dịch vụ Internet phương Tây muốn đặt chân vào Trung Quốc. Ngay cả một trung tâm sáng tạo với mục tiêu đầu tư tài chính cho các startup cũng không được chấp thuận.

Suốt 9 năm qua, Mark Zuckerberg, CEO Facebook, chưa bao giờ giấu giếm tham vọng đưa mạng xã hội lớn nhất thế giới trở lại. Thậm chí, ông nhiều lần tới Trung Quốc, gặp gỡ các quan chức cao cấp, gần đây nhất là gặp Chủ tịch Tập Cận Bình vào tháng 10/2017. Hồi tháng 3/2018, Facebook tuyên bố hợp tác với Xiaomi để cho ra đời kính thực tế ảo Mi VR Standalone. Sản phẩm này là một cách để Facebook có thêm những khách hàng công nghệ tại Trung Quốc.

Trong cuộc trao đổi với Recode tuần trước, CEO Facebook Mark Zuckerberg tỏ ra thận trọng khi bàn về chủ đề Trung Quốc: "Chúng tôi đang bị chặn. Thật khó để thực hiện mong muốn đưa cả thế giới gần nhau hơn mà lại bỏ qua quốc gia lớn nhất".

Google, cũng bị đẩy ra khỏi Trung Quốc chỉ sau Facebook một năm, cũng phải tìm cách đi đường vòng như đầu tư 550 triệu USD vào công ty thương mại điện tử JD.com...
