Well OK let's talk common sense.
I am buying a disposable item (maybe shaving cream or cookies). I will try cheaper brand (maybe walmart's or target's own dept. store brand) and if I don't like it no big deal. I am out maybe a couple of dollars. No regrets.
However if the railway plans to buy a locomotive (or I buy a cellphone) they are looking at a longer term purchase for at least a decade or more and they WILL care about payback and ROI. They will also look at after-sales support and maintenance contracts. If the Chinese supplier sells on price alone and does not live up to contractual obligations that is a serious matter. They will not be given repeat business. It is sad that most Chinese suppliers have trouble understanding this concept.
Blacklisting of Chinese suppliers has happened in Pakistan and now in Bangladesh with the DEMU fiasco- you can tell how serious this is when the PM of a country discussed this in a negative light.
Price is not the only factor when buying DURABLE GOODS. Price-to-quality ratio however is. What is also commonly called 'bang-for-the-buck' in the US.
That is why Japanese cellphones in the US (SONY) don't sell anymore because they are considered too pricey for features offered. People buy Korean cellphones or iPhones with a premium price (my last cell cost well over $1000). Will people buy Chinese cellphones? Maybe lower tier buyers will look at OPPO, Pocophone, Huawei etc. But mature buyers will not take a chance. They want dependability and functionality, not experimentation.
However some Japanese/Korean expensive TV brands and Microwaves are still doing fine in the US. They have a quality reputation built up over three decades and people will buy these 'durable goods' as opposed to disposable goods, even with a premium price. My TV's and Microwaves (both Japanese) are both over a decade old and going like champs (knock on wood).
I will always buy Panasonic Microwaves and Samsung TVs. Samsung TVs are not the cheapest, but I will buy them at a premium over a cheapest brand like (say HAIER) because I like reliability and better picture quality which only comes with good R&D. A Samsung 4K 65 incher will cost around $1800 at Costco, I have seen HAIER 65" TV's at Walmart selling for $600. I will still buy the SAMSUNG.
In microwaves too, reliability is essential (the Microwave tube and the electronics both need to be heatproof and reliable). No one wants to face angry womenfolk relatives in their home when a Microwave fails during a guest-event. Those are important considerations.
My time is much more valuable than calling support and dealing with an unreliable Chinese manufacturer who will not honor maintenance contract and warranty. I'd rather buy a better, more reliable product and have peace of mind.
There is a saying in Bengali "Cheap items have three conditions". Better to spend a few bucks extra and not have any regrets.
For third tier product manufacturers (who are forced to sell on price and don't care about reputation or customer loyalty because they cannot get it anyhow) there is a low-grade market too. But there are few takers for cheap goods for intelligent folks.
Ffor people like me (and experienced buyers in govt. and commerce), premium pricing is not a hindrance, if it comes with reliability and quality.
Volvo cars are these days made in China, but they are facing super hard time selling in the US. People know that these cars are not reliable (and they are made in China, not Sweden)- and they will avoid them like the plague. China suppliers have made this name for themselves.
Made in Germany/Japan means totally different things compared to Made in China when it comes to product quality and reliability.
