Where did you get that information? lol China is a mercantilist power. They are there for business and they sell to anyone who’s ready to pay. There’s no such conditions in normal business transactions
This one I don't disagree with because China puts business first and you'd have to really cross the line to anger China enough to have economic sanctions placed on you. Even then, a sincere apology and a showing in the right direction usually sets things straight very quickly. China does not want to waste time or resources against any country other than the arch nemesis, which is the US.
This is tied to China's philosophy of
not indoctrining its people with hatred even towards hostile nations with poor sentiments towards China. It was done long ago because under China's calculation, Chinese people with hatred and hostility are less likely to interact and learn from foreigners. Those interactions yield a net benefit to China from the perspective of Chinese people learning and returning to serve China, so they need to be fostered. In other words, returning foreign hatred with Chinese hatred is a draw, but returning foriegn hatred with brain drain against that country for China is winning against a foe.
Economically, China knows that each partner enriches China; the more bridges we burn, the weaker China becomes, even if the other nation suffers more and the impact to China is very limited. The added effects of many such relations with many small nations will accumulate into significantly greater Chinese national power with which China can face down the United States, or significantly less so the strategy is to keep eyes on the enemy King and ignore insults from pawns unless they cannot be ignored. Even if those small nations remain hostile to China to some extent, China calculates that with superior innovation and management, we can build ourselves and achieve more with what we get from their business than what they can do for themselves with what they get from our business, making the continuation of business a net benefit to China. So just like the example above, for China to cut business ties with a hostile country, it is either a draw or a small Chinese victory if such a small nation is economically harmed into diminished influence, but for China to continue business and use what we get from them to defeat their master, the USA, it is a crushing Chinese victory.
This is why China seems like such a business and benefits first nation.
