I think today any country that produces steel is capable of producing a steel alloy that is suitable for making straight razors from. The alloys that work well have been known for a very long time. You don't need fancy alloys to make a perfectly good straight razor blade from. You do need steel alloy made to a consistently high standard run after run after run.

The bigger question is do the actual makers buy the proper alloys, heat treat it properly, grind it properly and do that on a consistent basis. That usually does not happen when you try and make a product to the lowest possible price point.
