I know some japanese friends who could pronounce "R" and "L" correctly when speaking english. But they still said that they couldn't really distinguish between "R" and "L". That's kind of strange to me.

Our people say our language, Khmer, is a language without tones. I used to agree with that too until I met two korean students telling me how hard it was for them to learn our tones. I was really surprised back then about the tones thing, but yeah, what they said was right, our language does have them (the Chinese's 3rd tone, and the Vietnamese's 6th tone).
If you only speak our language, you can't pronounce Chinese tones correctly. However, most of our people do speak Chinese very well because they are Chinese related.
If you are used to languages with no space between words, you may not face any difficulty to learn our reading/writing. If you aren't, It really is hard as even if you have a dictionary, you wouldn't know what word you're trying to find it's translation/definition (e.g. we go to school -> wegotoschool, you may think "weg" is a word, or "wegot" is a word, etc.) As for listening, it's kinda hard because people don't really speak with the correct pronunciations. And for speaking, you have to use the correct level of politeness to whom you are talking to. We have around 10 words which means "I", ~10 words which means "you", ~10 words which mean "eat", ~10 words which mean "sleep", etc. Because people you talk to can be your parents, you lover, people who are older than you, people who are younger than you, same age, friends, king families, monks, people you really want to be rude to (when you have gone mad or some sort. You don't need to curse/dis them since using the right word can hurt them badly already.), animal too, etc. Using wrong words results in being ignorant/rude/too polite/weird/entitled much/whatnot. We also have male/female honorifics, and we have male "yes", and female "yes" too. :D
Our language is not the only one that use that kind of rule/logic, there are other languages out there that apply this logic as well.
