Coincidentally, China's first Mars (orbiter) mission Yinghuo-1 failed because it was hitchhiking on the Russian orbiter Fobos-Grunt that failed in an Earth orbit. India launched an orbiter soon afterwards and became the first country to get it right in the first attempt.

Russia retains an (rapidly diminishing) edge in certain areas of space. One of them is engine design. China is still keen on buying the best Soviet engines, namely Energia's RD-170 and its variants but of course Russia is less than keen on parting ways with them.

Even CALT, the major launch vehicle provider in China, admits it will be well into the late 2020s/early 2030s before they can get an engine as good as the RD-170. Their YF-130, while technically very good according to recent tests, is still a bit less efficient. Think about that, a 40 year gap. Aerospace is hard.

It isn't really the gotcha you think it is when you see Falcon 9s flying and landing multiple times a week, the most advanced conventional rocket engines ever being mass produced, two scifi-esque lunar landers under serious development and all the other things.

The American space program is far and away the world leader by a huge margin, while almost 2 decades ago things were dicey, the current Ameircan space program is definitely befitting of its glory during the mid/late 19th century.

They also created a bunch of tech that Americans thought impossible at the time - especially the staged combustion cycle with oxygen-rich preburner. And the American space programme too had its share of human losses due to sheer hubris - the 2 shuttle disasters included and possibly Apollo 1 as well. Let's not understate the achievements of the Russian space engineers and the bravery of their astronauts just because of the current political situation.
