What should I do if my visa application was canceled due to a discrepancy between my nationality and my passport's issuing country?

It is clear they made a mistake - would write them to explain China 🇨🇳 is the issuer and it is valid

When you replaced your passport in chiang mai, did you go to the Thai passport office and get a Thai passport or to the Chinese embassy/consulate? My guess is the latter, so your issuing country for your passport is China.

I’m seeing some other comments saying similar things. The nationality of the embassy or consulate you go to is effectively your country, even if it’s staffed with Thai people. The American consulate is a part of the American government, and same for the other consulates- even if your country’s consulate is a tiny office room.

My guess is that there are some situations where you can have a passport from a different country to your nationality. For example, maybe in some places permanent residents can get issued a passport for that country without yet being a citizen. Or in the case of stateless persons where a country issues them a passport but again they are not a citizen of the issuing country.

For the vast majority of people I think, unless in Africa or Asia they do it totally different, but from what I know, your nationality and issuing country are likely the same.

Put simply: what’s the country name of the office you got your passport? Or, when you look at your passport, what country does it say? It’s probably not a common scenario where people are issued a passport they’re not the citizen of.

Also, I just looked it up. At least for the United States there is a special case where non—American citizens can get a United stated passport. In that case their nationality would be X, and the issuing country the United States.

Reading this, I have now decided to apply in Taiwan, before they switch to e-visa in November, rather than Vietnam. I read in some posts that they will only accept payment if your visa is approved.

 in some rare cases, a country can issue a passport for another national. For instance, my friend from Syria has a French passport saying nationality Syrian. 

Issuing country is China but location Chiang Mai. Chinese embassy in Thailand is still a Chinese authority. 

How about your payment? Is it already deducted?

Uau , sorry to hear that. They should be more fllexiible correcting minor mistakes like this.

I also applied in Hanoi. Had my (Ukranian) passport issued in Thailand. No problem with obtaining visa. However I put Ukraine in the application.

There is nothing wrong as issuing country is Thailand.

Same issue. I'm German but my passport was issued in Jakarta (i got the passport from the German consulate in Bali). Im not sure what to put on the form... Germany?

I suspect you should have put the text from "Authority" for the place of issue but that's just a guess

I thought Chinese people was allowed to apply only in China? Still, I don't know exactly what happened, but as there are no refunds, the sole resource is to apply again.

Maybe in the issuing country you didn't choose China?

My passport is from Costa Rica, but I live in Korea.

My passport was issued here, it says: issued at Seoul.

But on issuing country I chose Costa Rica, not Korea, otherwise a mismatch would have occurred.

Do you mean your Nationality is Chinese and your passport issuing country is Thailand. Is it correct?
