so I don't think it'd entirely qualify as "chinese satellite", but yes definitely possible it's for a chinese market and with chinese components.

I think he meant Chinese "owned/bought" Russian made satellites. It is very likely a Russian satellite bus mounted with Chinese made 5G TR modules.

Why the rolling eyes? It isn't anything surprising.

The satellites are to be launched from Hainan. Also since this is 3GPP D2G and Russia does not have 5G or 6G system supplier, the Russian sats will certainly be integrated in a network built by Chinese companies like Huawei and ZTE etc. So I think Sputix is working as a component supplier in a Chinese driven infrastructure rather than Russian system.

Besides, I doubt Russian launching service provider namely Roscosmos have anything cheap enough to offer.

This is exactly what surprised me, that Roscosmos cannot provide launch of domestic satellites. Either there are no rockets for commercial customers, or it will be cheaper in China. And the legal issue of exporting Russian satellites abroad is not yet entirely clear.

Don't be silly. RSC Energia has a lot of spare capacity to make Soyuz rockets. It is mostly idle.
The private company just chose to do it this way. For all we know they might consider Roscosmos a competitor, they also make satellites, and not want to fund it. Or maybe price or availability wasn't right. It takes time to produce a rocket and maybe they ordered the launch at the last minute.

OrienSpace has just completed the first test run of the Force-110 engine.

OrienSpace has finished semi-system hot test runs of the LOX/Kerosene Force-110 engine, which fully verified the design of the turbopump and gas generator.
