Yang Wei stated that thrust vectoring will be used on any aircraft variant that needs it!

That's very true Siege, I'm wondering after they fly some of these technology demonstrators whether they will deem OVT the game changer it has been for the Flanker and F-22. The US has elected to build the F-35 without it, and I highly suspect the J-20 is just fine without it, and if my "fairy tale were to come true, I would build the F-22B or the YF-23 upgrades without it... I really think these 5Gen birds have such awesome aerodynamics that its almost overkill.... to boot you would gain some airspeed, useful load, and reduce your production and maintenance costs...

On the other hand, those Chinese Flankers would benefit to a great degree from OVT, I think OVT makes the Flanker the bird it needs to be, those Su-35's are exhibit A here....

The original designs for J20 calls for OVT on the 195kN class WS-15 . They’ll presumably stick to it unless something unpredictable happens.

Whether we will see 155kN class engines with OVT on the J20 is another matter entirely. There doesn’t seem to be a plan for it. Existing ones use the non OVT WS10, although it could have upgraded thrust.

ZHUHAI, China—An AVIC-owned J-10B testbed demonstrated in a Nov. 6 flying display showed China’s new mastery of extreme aerial maneuverability aided by an experimental thrust vectoring control system.
Over a crowd of thousands attending Airshow China here, the J-10B’s axisymmetric vectoring engine nozzle enabled several aerial stunts associated with the most agile combat fighters.

Thrust vectoring allows a pilot to control an aircraft in an aerodynamic stall condition caused by a low speed and a high angle of attack. By using the vectoring nozzle to rotate the thrust produced by the engine, the pilot can perform tightly controlled maneuvers in a condition that would cause most aircraft to depart controlled flight.

In the most dramatic stunt, the J-10B’s pilot pulled the nose back almost 90 deg., then used thrust-vectoring control to rapidly reverse direction in a maneuver known as a “J-turn.”

The J-10B also performed a familiar air show stunt by Russian fighters. Pulling the nose back beyond 90 deg. at a very low speed, the thrust vectoring system kept the aircraft in firm control.

Such stunts, while popular at air shows, have limited value in modern combat against another fighter. Post-stall maneuvering, however, can help a fighter pilot in other ways, such as by avoiding detection by flying with a forward speed lower than the threshold velocity required for being spotted on an airborne early warning radar.

Thrust vectoring technology has been available to Russian and U.S. pilots since the 1990s, but has entered China’s aerial arsenal only recently. The delivery of the first batch of Sukhoi Su-35S fighters earlier this year introduced thrust vectoring control technology to the People’s Liberation Army’s Air Force fleet. Around the same time, pictures surfaced of AVIC’s J-10B testbed equipped with a thrust vectoring nozzle.

The last paragraph is the highlight of the report. The reporter clearly knows that he can't accuse China of stealing or reverse-engineering the Russian TVC technology on Su-35S based on common sense and professional ethics. Yet he still could not resist the urge to drop the innuendo, against all common sense and professional ethics. It's almost feel like it's become obligatory, perhaps out of a sense of superiority, insecurity, patriotism or any combination of them.

This is not an exception, but rather very common practice when it comes to western reporting things about China. We've seen these kinds of tactics when it comes to Trump's trade war against China, with the accusation that China develop its economy based on "stealing of intellectual properties and forced technology transfers." We've also seen this in the reporting of South China Sea disputes, with the innuendo that "$5 trillion commerce passing through SCS a year" that could be endangered by the Chinese.

This is highly relevant here, because this kind of accusation is quite common in our area of interest here, the defense industry. We must constantly remind ourselves that "free" media is actually not free, and they're made up of people with their own bias, prejudice, ignorance and, indeed, agenda.
