China has already apologized and admitted a huge mistake (this is in their own news, I used google translate).
As for the thing you said about China not taking pressure: I think you're uninformed about what is going on in the world. China quite definately changes policy based on pressure they receive from the US. China is now the largest US debt carrier. Some people say this gives China power over the US, but they're severely mistaken. China's problem is that they have become very dependent on the US market (where they dump most of their goods).
The reason some people think this gives China power over the US, is because they say that if China asks the US to payback, the US will go bankrupt. This is true, but:
1) China can never do that, since the very reason they bought so much of US debt is because they're dependent on USA continuity and their willingness to accept China products.
T-bills are still major instrument for keeping currency reserve, as long as it gives reasonable yield, there is nothing wrong in holding them. However, if USD were to devaluate, then it is time to sell, and there is no stopping China from selling them in open market.
2) If China did do that, do you really think the US will let its economy collapse? It will simply not give a ****, and 'international law' (US+EU) will again close its eyes to another injustice in the world.
Sorry, can't catch what you try to convey.....
3) Practically all China's reserve money is in US dollars, even if they want to get rid of this, they would have to exchange at highest value against the euro. Which will still not change anything...
No, no all China's reserve money is in US Dollars, China also buy Yen and Korean Won bonds, and there is also Euro. The fact that China is the largest T-bill holders doesn't mean all China's reserve money is in US Dollar
In fact, this is what gives the US huge power over China. China has really put themselves between a rock and a hard place. This has allowed the US to have the upper hand against China.
