You've based your perception of China on fundamentally incorrect axioms, so there's no discussion to be had here. We can talk about radiation if you want.
They usually accomplish the goals they set out to do and have greatly improved the well-being of their people. Egregious corruption has been dealt with - that's old news. And there's no genocide in China. To say that is actually soft genocide denial as it trivializes the word.
China's Hongyanhe power plant releases 4x as much radiation lol. It's fake, unscientific concern being published for geopolitical reasons. I say this as someone who otherwise agrees with most of what the Chinese government has to say.
The Hongyanhe reactor annually releases 4x as many becquerels of tritium. The Fukushima metldown released 5,000x as much. So this is obviously a non-issue being drummed up due to politics. π
Probably Yenisei which unfortunately had its development paused.
A factor in this crash is that they lack a round-the-world comm system.
They've had this with GLONASS for over a decade. For far-side communications, you need a single relay satellite like what China used for Changβe-4. However, you don't actually need either of those for many lunar missions. When the Americans sent humans to the moon, they just used radio waves that were picked up from various ground stations across the world.
The plane just did that
