No need to overthink. Everyone will speak same language. Live peacefully. No use of gums and destructive machines. Rusiia and China will all speak in 'Enruma'. Enruma will be taught from Nursery and you can even obtain a degree in it from next year onwards. Oxford and Stanford are the first to offer higher courses in Enruma

Enruma, BTW is a mix up of English Russisn Chinese.... ma stands for Mandarin...
