How inflation in China makes real exchange rate between China and US to rise?
Chinese currency is not freely convertible. Its exchange rate is not determined by the market but rather by the Chinese government. Thus the counter-intuitive result. In essence, the Chinese government is subsidizing exports (which is reasonable since exports is what drives the Chinese economy).
Or maybe it's analyzing a critical aspect of the economic relationship between China and the US. US agricultural exports bring in over $100 billion each year, and China is a huge consumer of American-grown crops, meaning that whenever China cuts back on imports, American business suffers. NPR is an American radio station with an American demographic, which means that they are going to prioritize how the disagreement affects Americans.  The article does a good job of examining the nature of the problem, too. It doesn't read like a pro-Syngenta article at all. "Does some official tell the Foreign Exchange the the new exchange rate for the yuan is 0.98 * the current exchange rate? For China (and other countries with fixed/controlled exchange rates) - that's exactly how it happens. Does it just print more? This is the way to go for fully convertible currencies (like the USD, EUR, GBP, and handful of others, there're about 20 in the world). Flood the market and as with any commodity - flooding the market leads to a price drop. Obviously ""just print more"" is much harder to do than picking up the phone and saying ""Now you're buying/selling dollars at this price and if you don't I'll have you executed""." I've always understood inflation to be linked to individual currencies, although my only research into the subject was an intro economics course in undergrad and I don't recall seeing why that would be the case.  I guess the basic principle is that currency traders are watching the printing presses and trading in exchange markets to the point that the exchange rates fall in relation to increases in money supply. There's probably something about the carry trade in there as well, but it's late and I took some medications, so someone else will have to carry that torch. I must admit I've not really paid attention to foreign currencies like HKD, but the proximity and political relationship with China probably greatly complicates your question, since part of the problem has been China's currency peg. The Government doesn't borrow money. It in fact simply prints it. The bond market is used for an advanced way of controlling the demand for this printed money. Think about it logically. Take 2011 for example. The Govt spent $1.7 trillion more than it took in. This is real money that get's credited in to people's bank accounts to purchase real goods and services. Now who purchases the majority of treasuries? The Primary Dealers. What are the Primary Dealers? They are banks. Where do banks get their money? From us.  So now put two and two together. When the Govt spends $1.7 trillion and credits our bank accounts, the banking system has $1.7 trillion more. Then that money flows in to pension funds, gets spent in to corporation who then send that money to China for cheap products... and eventually the money spent purchases up Govt securities for investments. We had to physically give China 1 trillion dollars for them to be able to purchase 1 trillion dollars in securities. So it makes sense if you think about how the math works in the real world. The exchange rate between two currencies is simply the price that the most recent market participants were able to agree on, when trading. ie: if the USDCAD is 1.36, it's because the last trade that happened where someone bought 1 USD cost 1.36 CAD. There is no one person/organization which 'decides' the rate between two currencies. The rate moves you see is just the reality of money changing hands as people in various situations trade currencies for various reasons. Just like with stocks or any other market product, foreign exchange rates can fluctuate wildly based on many things. It is very difficult to forecast where rates will go, because the biggest changes in rates can often be unpredictable news events. For example, when Brexit happened, the value of the GBP plummeted relative to other currencies, because the market traders had less faith in the UK economy, and therefore weren't willing to pay as much to buy GBP.

There is a very high level of risk in the foreign exchange market; for your sake, don't get involved in any trading that you do not well understand, first. Inflation can be held at whatever level the international fiat banking system desires up until it hits the tipping point. Commodities are still high over a 3 year tracking (my uncle and cousin run a family farm of 1000 acres and they are in heaven this year with prices of beef, corn, and soy so high), and luxury goods are deflating because no one is buying them. I am going to speak in general, as this has also been the case in europe.  First of all QE is an increase of money supply but using non conventional measures(there might be exceptions) some examples of this measures are changing interest rates or TLTRO.  As to why this hasnt transitioned into more inflation, which in the end has but years after, has been a question that people have asked a lot. One of the reasons for this is the transmission mechanism not working properly, which implies that despite the fact banks have received money, they havent been able to move it to the real economy hence not increasing prices. It can take a while for inflation to seep into all aspects an economy and be felt by a consumer. Often, things that consumers use the most (like gasoline, wheat products, corn products, soy products, and sugar), are commodities spread across global markets with their own pricing which may be impacted by inflation in any given country.  Also, inflation can be beneficial in some ways. A $500/month mortgage payment was a big deal 30 years ago, and now would be considered trivial. That's entirely because of inflation.  Run-away inflation, where people are burning the currency to stay warm, is a different beast altogether. Be wary of people who conflate inflation, consumer pricing, and destructive currency devaluation, because they're not the same things.
