Hello~everyone,こんにちは、皆さん～

I am a Chinese. I can talk with you in Chinese.　I think 'I am a Chinese' can be correct, but it is more common to say 'I am Chinese,' 'I am from China' or 'I am a Chinese citizen.' You can say 'I am a Korean' or 'I am a Russian,' but there is a strange exception to this rule for China. The 'demonym' rules can sometimes be very confusing- even English speakers disagree about them! If you say 'I am a Chinese' English speakers will still understand you, do not worry too much about this rule. 

私は中国人です。中国語で交流する事できます。


Make friend with you I would say one of the following: 'I hope to be your friend' / 'Can I be your friend?' / 'Lets be friends' / 'I hope to make friends with you' (this last one may be confusing but it is just an expression, it really means 'I hope to be your friend' ... to 'make friends' with someone is to become their friend)

君と友達に成りたい。
