A correction. I would suggest Swiss, German, Austrian or Japanese. Japanese hand tools have a reputation for very high quality.
Japanese people have a cultural need to be perfect in everything, or else . . . been there, wish I'd have known to be more sensitive to this.
Chinese can make excellent stuff, e.g. war-planes & -ships. but normally they will be glad to tell you whatever you want to hear, but make the product however they please. Which is very, very unbelievably poor. This is true within China, as well as with the junk they ship here. Or so I hear from the metallurgist who replaced me. I've worked at educating him, decent success. We chat now & again, as I consider his high-temperature education to still be under (Ruger-style of) warranty.
Personally I would tend to avoid South American or Indian.
The two sources I noted are well known to many on this site, and have product from central European and Japanese producers.
