There is no need to wonder, the chief architect of the Great External Circulation already laid it out as clear as he could. China is more afraid of the dollar system collapsing than the US itself lol.
I posted it before here:
Wang Jian (王建) from China Society of Macroeconomic Research, who proposed the Great External Circulation strategy back in 1987 that was officially adopted by the central government, talked about this in an interview in the early 2000s:
中国是享受到美元霸权的好处最大的国家……美国巨大的贸易逆差,是对中国产品的巨大需求, 拉动了我们经济的增长……我们现在要担心的是,美元贬值引起国际金融大动荡,美元失去国际的货币的霸主地位,没有能力继续用经常项下的逆差来拉动亚洲,特别是对于中国的经济增长的影响,这才是最可怕的事。”
China is the greatest beneficiary of the dollar hegemony… the huge trade deficit of the US also represented a huge demand for Chinese products, and spurred our economic growth… What we have to worry about now, is the global financial instability caused by the depreciation of the US dollar. If the dollar loses its global currency hegemonic status, it will no longer have the capacity to sustain its deficit to drive Asia’s growth, and this will especially affect China’s economic growth. This would be the most terrible thing to happen.
In September 2020, months after China proposed the Dual Circulation Strategy (export balanced by domestic consumption), Wang Jian reasserted the importance of dollar hegemony in an interview:
中国是最依靠美元体系的国家,因为人民币没有国际化,而欧元、日元、韩元等都是国际化货币。过去,中国一直享受着美元霸权的好处,人民币不是国际化货币,但是中国的生意可以做到世界最大,因为中国用美元结算。如果美元体系崩溃,即美元作为储备货币和结算货币的比例发生断崖式下降,比如从60%下降到30%,受到伤害最大的一定是中国。 所以在 “十四五”期间,一旦美元出问题,会对中国产生非常大的影响。
China is the country that relies the most on the dollar system, because the RMB is not internationalized, whereas the Euro, the Japanese yen, the Korean won, are all internationalized currencies. In the past, China has continuously enjoyed the benefit of the dollar hegemony - the RMB is not an internationalized currency, yet Chinese businesses can expand to become the world’s largest, because transactions in China are settled in US dollars. If the dollar system collapses, then the proportion of the US dollar as a reserve currency and settlement currency will fall steeply. For instance, if it drops from 60% to 30%, the country that is hurt the most must be China. Hence, if the dollar system encounters trouble during the 14th FYP period (2021-2025), it will cause great impact to China’s production.

Once you understand this, you will understand that China cannot and will not give up the dollar system, especially its hegemonic status. The status quo greatly benefited the Chinese economy and there is no reason to give up even when the US itself is threatening to end the arrangement, because China still has plenty of cards to play (e.g. rare earth export). The US will find itself unable to decouple from China.
This is also why when the US confiscation of Russia’s $300 billion foreign reserve at the start of the Russia-Ukraine war, and the Fed rate hike that caused dollar liquidity crisis in many Global South countries and spurred strong interest in many to leave the dollar regime, China has been the one that was and still is the most reluctant to abandon the US dollar. If China doesn’t want to, then nobody else can do anything about it. The Biden administration correctly gambled that China would not threaten the dollar hegemony during the rate hike in 2022.
Your example of Spain with the stagnating wages (stagflation) is why, as I wrote in the original comment, that workers are feeling financial strained.
However, believe it or not, deflation itself is even worse!
You may think if products are getting cheaper, the purchasing power of the consumers will increase. Yes, but only up to a point.
Neoclassical economists think there is no difference between the scenarios because they treat money as a medium of exchange. But this cannot be the case because money is debt…
Consider the inflation scenario:
You have $1000 income, Treat is $100 a piece. If you take out a $2000 loan, you can get 20 Treats this month.
Next month, your income has doubled, so you have $1000 + $2000 = $3000, you use $2000 to pay off your debt, you still have $1000 left in your bank account that allows you to afford another 5 Treats if you wish!
Now, consider the deflation scenario:
Same as above, you take out a $2000 loan to consume 20 Treats. But next month, your income is only $500, you have a total of $1000 + $500 = $1500 but with a $2000 debt to service. You are $500 short with no liquid cash to afford more treats this month.
Of course it’s an exaggerated scenario, but it very much reflects how money works in an economy. First, consider the business sector:
For many private firms, they take out commercial loans for investment, for expansion of production, hiring workers etc. Under an inflationary scenario, the loans become cheaper to service, wages can be raised etc as long as profit is expanding. This also means you can hire more workers, expand productive capacity which will lessen the inflation over time.
But under a deflationary scenario, your profit margin gets squeezed (prices become cheaper = profits falling) but you still have the same amount of debt to service. There is no good way out of it - you can’t pay your workers more, and as they receive less wages, they will consume less, which means the deflation gets worse over time, and more workers become unemployed as a result!
Now let’s consider the household sector, which is very much the relevant situation for the Chinese middle class today.
Let’s say you purchased a house at $100k. Now you may say the price of the house is irrelevant because you’re not interested in speculative investment, you just want to stay in it.
But does it really not matter? Can you make sure that you can stay employed over the next 30 years of your mortgage?
You bought a house at $100k, the inflation has made your house worth $150k. We’ll dispense with how much downpayment and how much you already paid for the mortgage because it’s too complicated.
But let’s say you lose your job and can’t find one in months. Your savings is running thin. At this point, you can sell your house and take the cut (say $30k after all the expenses) and downgrade your living condition to a cheaper rental place. You now have a $30k buffer to get through the unemployment.
But if the deflation has made your house worth only $70k, you’re pretty much screwed!
First, it’s unlikely you can see your house, because who would want to buy it at $70k when it could be $50k next year? Not only are you already making a loss in real time, but you’re not even allowed to cut your losses!
If you choose not to default on your mortgage, you still have to pay that $100k + mortgage over the full 30 year period, while having lost your entire income!
This means austerity, cut all spending and use whatever you have to keep servicing your loans, and this automatically translates to less consumption, contributing to the deflationary spiral of the economy.
As the middle class spending stops, the economy begins to stagnate. These two situations are very real in China right now, and it is made worse by the fact that there is little to no social safety nets in China, unlike European countries.
