The one thing we should learn from this is all countries are up to something. The US is having a go at China, but why?
That's an easy question to answer - Cash and power (as usual). China's OBOR is taking chunks out of the US's influence (Trump helped them by being a dick), and BRICS is hammering the petrodollar.
China's influence is taking over, but they're doing it with loans, building infrastructure, and getting countries into massive debt - Probably better than bombing the hell out of people as the US does, but still not nice.
As for China building military bases on islands - of course - they have to in order to counter the US carrier threat.
You may have noticed a massive US military build up since Obama's announcement of some years ago. Do you really expect China to ignore that?
Of course, propaganda tells up about the Chinese military build up, but forgets to mention the US started it.
Now we come to oil supplies, and how the US has set themselves up to blockade China's oil and coal. China replied with massive investment in renewable energy, energy storage solutions, and EVs - Now they're way ahead of the US on that as well.
Now, shall we look at how China invested in RREs while the US was closing mines, or shall we skip that save to mention the US now relies on China for it's most advanced military hardware - That including the F35?
One of Trump's more idiotic moves, his attempt to grab Greenland, wasn't quite as stupid as most think. The truth is that country has large RRE deposits and the US wants them. The fact Trump went at it like the moron he is means little, but that was the real goal (In my opinion).
However, the long and the short is all this China thing is a cash thing - Nothing to do with democracy or human rights.
