In my country the joke is that Chinese people pronounce the R's like L's.

You do realize that "asian" is neither a nationality nor a language? That asia is home to a great number of different languages... now I noticed your name and I don't think you're someone who'd understand that...

Yes, but.. Lefligelatol.

Exactly, so how do we know if they're trying to pronounce an R or pronounce an L and it comes out making the R sound (context)? If you knew this stereotype and assumed that when they said anything with R in it they were actually trying to say L, like a jackass, you could get it confused I suppose. But this content is **** and OP is a jackass.

Let's make this clear
Chinese = there "R"s turn to "L"
Japanese = there "L"'s turn to "R"s

And seeing that Kim Jong Un is Korean neither is relevant. When it comes to Korean pronounciation the ㄹsign is used as both R and L. Generally it is pronounced as R when placed between vowels like in 사랑 (sarang) which means "Love"

Yes the Korean R is much harder and has more vibrating sound then english R. Which is fine by me as my native language has the same pronunciation of R

there are asian countries that can pronounce the L and R perfectly, an example would be Philippines.

Well I don't know much about Philippines I just wanted to provide some additional knowledge

well, that's one fact that was truly fun
