It looks like the problem isn’t with the tests, but rather they are buying uncertified products.

From the first link,

> the company that made the test kits, Shenzhen Bioeasy Biotechnology, had not been on Beijing’s list of certified providers

> Spanish health officials said they bought the tests from an unnamed third-party distributor

Furthermore, the Spanish health officials used the test wrong,

> In a statement on social media, Bioeasy said that Spanish officials did not understand how to conduct the test and that it made videos and issued instructions to help them.

If I'm following this mess correctly, that list of certified providers didn't actually exist when Spain placed the order which would make it rather hard for them to make use of it.

Exactly. The test worked very well in South Korea.

Why would South Korea use Chinese testing kits when they are at least 4 biotech companies making their own testing kits (and for exports)? South Korea companies developed testing kits almost as soon as the Wuhan virus became known and have been using their own in all domestic testings.

South Korea made their own kit if I remember correctly.
