Are there any words in common in pure English and pure Chinese or Japanese?
There are many words in ancint Persian with the same meaning and pronouncing in English, but I don't know if is it true about the Far East's languages.
From my understanding, no. European languages, including Russian, including all the Indo-European languages, go back to Sanskrit (which I am studying) but the western Asian languages including the Chinese and Japanese languages have different roots. That's my understanding. I am not expert, but it's what I have read.
I guess some words in English would share a similar root with words in Farsi (aside from borrowed words). That's to be expected.
I'm surprised you just asked about a couple of languages. I've found cognates with basic Farsi words in Russian and even Irish Gaelic.
