Yeah if you know you know.
The moves Russia is making with Ukraine {plus other invasions in the recent past} and China wanting Taiwan are tied together.
Right now China can not support the fuel needs for it's country ( I think it's like 25% ). That's why they have to export so much from other countries. This also comes with a not so hidden secret. If you block the Malacca Strait then China will have just under 4 months before they can no longer power their country's fuel needs and less than that if they have to allocate country fuels to the military operations.
This is why China has been making deals with Russia and dumping a bunch of money into Pakastan. They also want to get as close to the Caspain Sea as possible because they found a bunch of Natural Gas reserves there. Their goal is to link with Russia for it's fuel needs and to offset the Quad [ Australia, India, Japan and US] by basically finding other trade routes that can't collapse it's economy via a naval blockade.
Right now China doesn't have enough Naval Carriers and etc. to match the US... but they did go from like 2 vs the US's 20 to 5 in a very quick pace. They have also been attempting to basically build random Sea islands for military outpost to offset the countries around it oceanic coalitions.
It's a cat and mouse game but right now China has to talk tough until they get their infrastructure how they want it and then they'll try to flex more.
