I don't particularly have an issue with the positions themselves, but I'm kind of sad that those african countries are just leaving an issue and welcoming another. It is true that the infrastructure are being developed but then the countries are not developing because they don't benefit long term. You could argue that they will benefit from better transports in general which is true but it only holds up until China is doing fine economically (which it isn't exactly today).
I don't care if it's a western country or not I'm just trying to find what would benefit those countries, and it doesn't seem that buying everything there will (or putting soldiers with other colors and ideas)
Their growth decreased quite a lot but they're still not entirely a developed economy. The real estate bubble kind of exploded leaving quite a lot of people on the side.
They have a demographic problem due to their past policies, social issues with work, the fact that you can't find a job after 30, and their wages being reduced by a pretty large percent (my sources are saying around 30-40%, can't find an official number because they do not exist).
It's the first time since a really long time that China came back to a single digit growth and this is not something you revert in a few months. It's not the end of China or anything but they're definitely not at their highest and won't be for some time. Meaning that political long-term investments may not be the priority and that they may give up those whenever they want, not when the country that benefited those will not need them anymore.
Again, not saying western countries are doing much better. But some are doing relatively worse than what they should be doing than others.
