Dear Sir or Madam，
Have a nice day!
Hope I am not bothering you. I am writing to approach you for future business.
We are one of the leading manufacturers of palm oil in China, and we wonder if we could commence business with your firm.
If we can be of any help in the future, Pls do not hesitate to let us know.
It would be pleasure to receive an answer from you.
I’m awaiting your reply
