Laying the foundation stone for a system integration laboratory for C929. Once completed, the lab will be in charge of integrating the various mechanical, electrical, avionic, flight control, and hydraulic subsystems for C929 to ensure they meet performance and lifecycle requirements.

Closest thing to an official announcement that C929 project is back and live, and that CR929 project is abandoned.
I've told you before
You overestimate Russia
Old technology has no meaning
It is no longer feasible to rely on the legacy of the Soviet Union
The source of information I have is more reliable than yours.
Russia has no technology and no funds
I also want to defraud China’s technology and funds.
But China is not India
Russia no longer has any military technology worth China’s cooperation with
Or it can be said that Russian nuclear submarine technology will not be given to China
But it doesn't matter. It won't make sense for China anytime soon.
Chinese strategic bombers will soon appear
New nuclear submarines will also appear
Engine technology will soon surpass Russia's
China’s huge capital and talent utilization
Achievements over the past 40 years
It is not comparable to a country with stagnant development and lower military expenditure than India.
Russia's pride can now only be obtained through bragging

What I said is true
But you should be a spiritual Russian
It's really shameful to ban my account.
Bragging cannot make a country strong
This is only possible with huge capital investment and talent investment
Welcome to the Russian Fantasy Forum russian military forum
I enjoy watching the imagination of a group of dreamers every day
The PD35 engine mentioned by those above will definitely not be used in China.
Too backward

It is pretty retarded that he is saying that Russia is relying on the legacy of the Soviet Union the day after Russia successfully tested Burevestnik. So tell me who else has a working airbreathing nuclear engine at this time. Let alone one of such minute size. Even the supposedly "simple" Russian strategic systems like Poseidon require a level of nuclear reactor miniaturization unavailable in the West. People laughed at Putin's presentation on new strategic weapons after the US pulled out of the ABM Treaty. Some people called them "Putin's cartoons". Well a lot of people aren't laughing anymore. Another example of one of those systems would be Zircon, a scramjet powered missile. The US has been working for decades on scramjets, but still has no operational system. Well the Russians have it and it's in serial production.
Aviadvigatel at Perm has worked non-interruptedly on large turbofan engines for decades. And successfully developed several engines including the D-30, the PS-90, and the PD-14. Also, unlike what you are saying, the PD-35 engine is using leading edge engine material technology including composite fan blades, and ceramic matrix composites. Russia is also one of the worldwide leaders in 3D printing of metals. So it is quite likely that will be used in the engine as well.
If China wants to use the PD-35 engine or not in the C929 when it is available, it is their own choice. But Russia will develop this engine. They need it for several programs. Heck, just selling land based versions of it to Gazprom for pumping natural gas could probably give work to the engine builders for a couple decades. Today they sell to Gazprom the PS-90. They sold dozens of those engines for the Power of Siberia pipeline alone just to keep the gas moving.
You say Russia does not have money. But like I already told you, Russia is currently building over 14x GW class nuclear power plants abroad. 4x in Egypt, 4x in Turkey, 4x in India, 2x in Bangladesh, plus several more in China, Hungary and elsewhere. Most of these are being built with financing by the Russian government. Each power plant costs like $6 billion USD. 14x6 = $84 billion USD. So the Russian government is loaning tens of billions at low interest rates to other countries. And you tell me they cannot partly fund an aircraft program? For reference the whole A350 program is supposed to have cost $15 billion USD. Which is about as much as Russia is loaning Bangladesh for their two nuclear reactors.
A lot of Western analysts don't understand why Russia is still financing both the Russified MC-21 and Superjet 100 programs simultaneously given the expenses in the conflict in Ukraine. But the thing is, Russia has plenty of money to do both programs, and they will essentially pay for themselves. Making a C929 class aircraft by themselves and just for themselves though, is way more debatable for Russia economically. But once they have the PD-35 engine available and in production, that is like half the development cost for making an aircraft.
Hopefully China will develop the C929, and make it independent of Western parts, so that it can be sold not just to Russia, but also Cuba and other countries under strict US sanctions. If not, then Russia will like use the PD-35 in a new wing with the Il-96 body.

A lot of people are really funny. When Western fanboys knock off Chinese tech they go completely nuts but when they knock on Russian tech, on which a lot of Chinese military tech is based, they are all of a sudden legit.
Digression: This statement is controversial.
The second stage of testing the gas generator of the PD-35 engine took place at CIAM
16.10.2023
Central Institute of Aviation Engine Engineering named after. P.I. Baranova and the Perm design bureau of UEC-Aviadvigatel JSC tested the gas generator of the promising high-power engine PD-35. The first start of the gas generator at the second stage of testing took place at the CIAM complex, the largest in Russia and Europe, for full-scale testing of aircraft engines in Moscow. Tests of the “heart” of the PD-35 exceeded expectations, valuable information was obtained for further work, reported in the press service of the Rostec state corporation.
During the tests, the operation of a full-size engine was simulated, and more than 1,500 parameters were evaluated. For this purpose, CIAM specialists created special bench equipment and software. “The obtained parameters agree well with the design data. They gave the engine developers valuable information and extensive experience that will be used in further work,” Rostec noted.
They added that the power plant being developed by the United Engine Corporation for long-haul aircraft will be a real giant - there have never been such aircraft engines in our country. The diameter of its fan is 3.1 meters, the thrust is 35 tons. The developed gas generator will subsequently become the basis for the creation of engines in the thrust range from 24 to 38 tons.
In September 2021, the PD-35 gas generator demonstrator was tested in Perm, which was installed on a closed test bench and tested under standard atmosphere conditions. Now, as part of the second stage of testing, the operation of the gas generator has been tested with the supply of heated air under pressure to its input, which simulates the operating conditions of the unit as part of the engine.
The PD-35 engine can be used as a power plant both for the creation of passenger wide-body airliners, for example CR929, and for heavy transport aircraft with a carrying capacity of one hundred tons or more. It is assumed that the engine can serve as an impetus for the remotorization of the passenger Il-96-400M into a twin-engine version, as well as replace the Ukrainian D-18T with the cargo An-124.
According to the Deputy Prime Minister, Head of the Ministry of Industry and Trade, Denis Manturov, it is planned that the PD-35 will appear by 2030, while its thrust may be below 35 tons, the exact decision will be in the spring of next year.
“By 2030, an engine with the working name PD-35 should appear. It’s not a fact that it will be 35 tons, it will most likely be smaller, with a thrust of 26 tons to 35 tons. In March next year, we will understand more precisely in what form the engine will be created. The engine demonstrator is planned to be manufactured in March 2024,” he said.
The development of the PD-35 engine began in the summer of 2016 at two enterprises: Perm ODK-Aviadvigatel and Rybinsk ODK-Saturn. It is assumed that the PD-35, unlike the previous modification PD-14, will have 16 tons more thrust. The total investment in the engine creation project is 180 billion rubles.
