Hmm? An official confirmation for the drop out?

yeah. almost an official statement ..

at the International Military Technology Forum "Army-2023" (ARMY-2023) held in Moscow, the general manager of UAC admitted in an interview with a 24-hour TV channel that his role in the CR929 project has changed from a partner to a major supplier...

it is probably a logical decision, probably the C929 will incorporate numerous components from countries considered hostile by Moscow, jeopardizing a possible co-production of the aircraft in Russia and the subsequent use by their airlines. If I'm not mistaken, Russia had asked to make a version without sanctionable components, receiving a refusal. On the other hand, in the current situation with the reciprocal closure (Russia vs USA + allies) of overflights and commercial tourist destinations, the need for aircraft of the C929 category has been considerably reduced, needs which can also be met by the IL-96 (aircraft free of foreign components) of which there is a redesign study to be able to use 2x RD-35 turbofans instead of the current 4x PS-90 turbofans in the new aircraft produced.

My question is, if the U.S. changes its mind later and decides to sanction Comac, will Comac revisit its decision not to work with the Russians on a sanction-proof version? Will the Russians still be willing at that point?
All the events inherent to this commercial aircraft and the global situation in which sanctions and embargoes are the sword of Damocles that always hangs over the supplies of "Western" partners of components, leads me to think that without publicizing the collaboration to build an XX-929 with only Sino-Russian components it will continue, this for having it available for production in the eventual and hopefully never repeating for China of what happened to Russia (and not only) with the imposition of sanctions on the commercial aeronautical sector

I don't understand why COMAC couldn't sell the major components produced with Chinese IP to Russia for their assembly.

maybe i'm wrong, but the aircraft is not only designed with chinese and russian components, but the design currently incorporates parts with patents from countries currently subjecting russia to sanctions and embargoes, so the same problem that arose with the russian aircraft SSJ-100 and MS-21 .
In any case, some aeronautical components with a Chinese patent, if compatible and not already produced in Russia, will certainly be used on the new aircraft under production in Russia and not only for the two aircraft mentioned above, but possibly also for other aircraft for regional flights and premises currently in the testing or planning stage

The Russians dropping out of the C929 project was likely influenced by the decision to support their own domestic industries. About 1 week after the announcement by UMC to drop out of the C929 project. They were reporting that the SSJ-100 made their first successfully flight while being built with domestic components. Doesn’t make sense for UMC to pursue the C929 while their own subsidiary is making the SSJ-100 with federal funding.

Shares of Russian state-run aerospace company United Aircraft Corporation (UAC) soared 45% on Tuesday after the maiden flight of the country’s first fully domestically-built aircraft.

Earlier, the Russian Industry Ministry said that an SSJ-100 equipped only with domestically-produced components had carried out its first flight. The airliner flew at altitudes of up to 3,000 meters (9,800ft) and speeds of 343 kilometers (213 miles) per hour.

yes, but SSJ-100 or as it seems to be renamed SJ-100 equipped only with Russian components is to be considered of the ARJ-21 class, but the Russians are also building MS-21 without foreign components, aircraft of the C-919 class.
Instead, the C929 is a wide-body aircraft with long flight range, of a class such as A350, B777 etc., and the only current Russian aircraft of this category and the IL-96 is a non-modern design also due to the type of turbofan used, also made only in 1 or 2 each year.
Therefore, the modern C929 could meet their needs, but the current sanctions situation towards Russia would put the use of the C929 at risk if it is made with numerous Western components.
So if I remember correctly, Russia had asked to build it solely using Russian and Chinese components, but the Chinese side, which has other needs, prefers collaboration with companies from the Western bloc countries, probably for this reason the C929 if used even by Russians, it would become subject to sanctions and therefore difficult to use, probably for this reason the Russian companies and state withdrew from the partnership, although possibly offering some components.
On the other hand, as I have already written, currently in Russia the need for long-range wide-cabin aircraft is very limited due to the ban on overflight of countries adhering to the sanctions, and for 5-7 years the current Boeing and Airbus are sufficient, next to them some IL-96s that are in storage and brought back into service and still have many useful flight hours,+ some newly produced IL-96s (an aircraft already completely made with Russian components) including the cargo versions.
It seems that they are working on a modernization project of the IL-96 project to adapt it to the use of 2 RD-35 Turbofans instead of the 4 PS-90 turbofans currently and with only 2 crew members in the cockpit.
The facts demonstrate that if some strategic sectors such as civil aviation, naval engines, etc. of a large nation become dependent on the supplies of countries which for various reasons can then impose sanctions putting not only those sectors at risk, it becomes almost mandatory for these great nations work to have their own productive autonomy in the sectors.
The Russians perceived this in 2014 and then immediately completely in 2022, their luck is that even if much reduced compared to the Soviet era, they still had an aeronautical industry that has the capacity to create almost all the components, including an entire family of modern commercial turbofans, it certainly took time and will still take time to have an adequate production (in numbers of aircraft produced) to replace the fleet of Western aircraft, but the path has now been taken.
