Should also be easy to read Cong as "Tsong' since it would literally be read it as we see it. But commentators still pronounce it as "Kong" for some reason....
If we're talking about British/American/Canadian/Australian, etc. commentators, in English there would never be the soft "C" with an "o" after it.... although if we gave it some thought, we might come up with some exceptions to the rule. But unless we'd studied linguistics or a few diverse languages, or otherwise know to question it, native English speakers would probably say "Kong."
