But code in any language can be read by any engineer in the world that is proficient in it. I do not speak or read Chinese but when I pull an interesting looking repo from Github that is Chinese I only have to stroke 3 keys to translate all python comments in the file to English. Works great!
You don't need really need another language when you have a common one in place. Even without code comments you should be able to sniff out the crackpots.
Chinese repos are trending on Github everyday. They do really cool things beyond the cutting edge on every side of our business. From frontend react and vue to shiny ML and backend golang.
