Meh. People believe too much that China is a charity. Look at Syria, Afghanistan, and now at Ukraine. Do you think China will heavily invest in any of these countries without significant strategic concessions and other demands met?
For Ukraine is even worse, who says that China goes and invest, lets say, $100 billion, and Elensky the day after pulls a Motor Sich 2 on China?
Joke on them, China isn't a fool. It shows the enticing carrot of practically unlimited money to invest and this keeps the other countries in line to "please" China. However, reality isn't so rosy. China will only invest when it believes the time is right and that its investments are safeguarded with strategic concessions and other collateral
In the meantime, China will sooner throw $100 billion to African countries plagued by coups, wars, instability before it touches Ukraine. At least with Africa, China more or less knows what is getting. With Elensky you get a new surprise every day. Today is Motor Sich, tomorrow he provokes the great power next door, next week is disaster, next month the country is gone lol
In any case, Ukraine as a country is done for, so there is no need for China to bother with it. Might as well as go and talk with Putin
