The problem with the idea of China buying more Mi-26Ts is that it might not be what the PLAN needs. While the Army might not be constrained by size requirements the Navy most certainly is by the hangers of their amphibious transports. It is mighty hard to fit a helicopter that is larger than a Chinook into one just saying.
And with the 075 just being launched, the timeline of 2032 is indeed a rather long way off. So for the time being the PLAN Marines would be forced to rely on the Z-18 for the majority of their vertical lift capacities.

What does the "max internal load being 10T or 5T" mean? Both figures are for the same altitude.
Are max external and internal load being reached simultaneously? (I doubt). If not, what is the max combined load.
Could the 5T max internal being the number when max external is 15T? That would mean the max load is 20T.

Nah, I don't think 4500m applies to 10t - it's probably supposed to be read as applying only the figure after the /, i.e. 5t. Granted, the way it's written is open to misinterpretation, but it makes sense to me if understood in the way indicated. Helicopter lifting capability deteriorates very badly with altitude, to the point where plucking a single victim off a mountain significantly above 6000m generally requires minimized fuel load + any rescue personnel other than the pilot to be flown separately + any non-essential equipment, including the doors(!), to be taken off + taking advantage of translational lift and slope for take off on the return leg! The payload margin becomes *paper thin*.

Stating something like "Max. internal load (@ 4500m).................10t (5t)" would probably have been less confusing.

Russia signs contract to develop new heavy helicopter with China

Mon, November 8, 2021, 12:28 PM

MOSCOW (Reuters) - Russia has signed a contract with China to jointly develop a multipurpose heavy helicopter, state-owned Russian Helicopters said on Monday, in a sign of closer technological cooperation between Moscow and the world's no. 2 economy.
Russia will contribute parts for the aircraft including its transmission, steering screw and anti-icing system, the company's Chief Executive Andrey Boginsky told President Vladimir Putin, according to a transcript on the Kremlin's website of their meeting.
The contract builds on an agreement signed between the Russian and Chinese governments in 2016 for China's Avicopter and Russian Helicopters, a unit of state industrial group Rostec, to develop a heavy helicopter for the Chinese market that would be assembled in China.
Russia has been in talks about the project with China since 2008 and the contract was signed on June 25 this year, Boginsky told Putin. He said the contract would last about 13 years, but did not disclose other details.

Russia pivoted to China in 2014 as its relations with the West plunged into acrimony over the annexation of Crimea from Ukraine.
China is Russia's biggest trade partner and Kremlin watchers have been watching for signs of closer cooperation between the two governments as they have both sparred with the West.

What about the engine? Last I heard of it this was supposed to use PD-12V gas turbine but there are no news of its development. Klimov is already busy with VK-1600 and VK-800 development. Aviadvigatel is busy with PD-35 and PD-8 development.
Mil Mi-26 used Ukrainian D-136 engine which for obvious reasons won't be available.
