Perhaps I should have said that, while China and Russia are both very concerned about their image inside the country (showing that they have some fear of their own population, perhaps), China is much touchier about its image outside the country.
Russia's GDP is about 2017USD$ 1.7 T.
China's is 2017USD$ 12.2 T.
Companies traditionally aren't in the habit of doing favors for inconsequential entities. And for non-energy multinationals, Russia is generally more trouble than it's worth.
GDP/person: China $8,609, Russia $11,805. It's complicated to compare these two countries. China has a much larger economy so they have a bigger pool of money to spend, but then they have less per person. But both countries have huge poor groups.
