That's your statement not others. China never "rejected" US bonds, they dumped it because they wanted to reduce the amount of risk they were taking since US dollar started tanking (crash postponed by hugely increasing interest rates) and US-China are practically in an economic war. This is also not the only thing they did. They've been pulling out of each other's markets for the past couple of years. For example in the most recent news Apple revealed plans to pull a big part of its production out of China and move it to India.
There is a thing that I don't understand. Some years ago I remember Apple or Barak Obama stated that Apple couldn't move factories from China to other country because Chinese laborers were highly qualified, efficient and fast. So, I don't really understand, if America is so dependent on China, why does China heavily invests in U.S. Treasury bonds and makes its own currency weak to keep low export fees? It could profit more if the USA is really dependent on China.
And there is another thing that I personally think is a huge bullshit. Why doesn't America produces goods in the USA? Labor is expensive? Then they shouldn't produce food, shouldn't provide postal service, shouldn't do tons of thing if we think that way. And labor isn't that cheap in China too. I think they are just exploiting their employees and they wont' be able to do the same in the USA. Or may be? Idk, I have heard that Amazon exploits its warehouse and delivery employees too.
1. China has an export-oriented economy, that is, China has a positive trade balance. In such conditions, it is beneficial for China to artificially maintain a low exchange rate of the yuan.
2. China is actually a monopolist in the production of a large number of rare earth metals, which are actively used in any high-tech products. This is a strong trump card of China and the answer to the question why it is difficult for any large company to transfer production from China to any other place.
The reality is a little different.
China is really the leading supplier of gallium and germanium today. This is a fact, I confirm. But I highlighted the word "SUPPLIER" for a reason. The fact is that these rare earths are also mined by other countries. The advantage of China, before the introduction of "licensing", was the extremely low price. But there are deposits of these metals in other countries, and in industrial quantities, with a slightly higher price.
The countries with the largest deposits and commercial production of these metals:
Gallium - Japan, South Korea, Ukraine
Germanium - Canada, Belgium, USA
Yes, they will create a temporary inconvenience, but it's like another "fighter against the world" with "turn off gas to Europe. Remember how it ended? There were "predictions from international analysts" blaring through all the outlets - "Europe will freeze, die out and crawl on its knees".
In the end, the EU quietly switched to alternative and adequate suppliers of the "unique product", and ... in the end - the EU has no problems, Russia has lost this market forever.
The same will happen with Galium and Germany - China will simply lose supply contracts, it will take some time to sign new contracts, build logistics schemes, after which China will be told "goodbye our stupid supplier
China made a far-sighted bet on rare earths in the 1980s. Today, China is the world leader in the supply of 17 different rare earth metals with a market share of about 90%. To capture a significant share of this market requires huge investments and years, if not decades of directed efforts. The irony is that rare earth metals, which are actively used in high-tech goods, including for the green transition, are extremely unfriendly in their production, so replacing China on the world market is not only long and expensive, but also very dirty work. The production of rare earth metals is one of the reasons why in some parts of China it is possible to make bricks from the air, it is so dirty. Want to replace China? Good luck.
Let's start with a theory, shall we?
Rare earth metals are a group of 17 elements including scandium, yttrium and the lanthanoids (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium).
Galium and Germanium are not included.
What I agree with, and it is foolish to deny - China is the largest supplier of rare earth metals today. But not EXCLUSIVE.
You can read in open sources, about deposits and mining of this group of metals in the world. Note that until 2000, the leader in mining and production of rare earth metals was the USA.
There are also large deposits in Australia, India, Brazil, India, as well as other countries.
The above-mentioned "problem" concerns only 2 metals - gallium and germanium. But as you know - their production in other countries has been reduced, but not stopped. It was just logical because China started to supply a lot of these metals to the market cheaply. Now other countries will start to increase production of these metals, because there is demand, and there are "restrictions" from China.
In a word - there will be a small adaptation of the market, as a result of which - new and old suppliers will simply appear on the market, with prices a bit higher than Chinese prices. Let me remind you once again - without being a really exclusive producer of some goods on the market, it is foolish to make such steps. China apparently has not studied Russia's experience of economic terrorization of consumers, and may repeat its history in another segment of the resource economy.
PS Regarding dirty air, I also agree. But there are nuances
China has never cared about ecology and public health, so they did not use quality technologies to ensure environmental safety...
