I am writing this letter to express my apology for the inconvenience I brought to you, with the following being the detailed reasons.
The most important thing I want to talk about is that I am sorry that I have to cancel my travel plan and can't visit you this time. Actually，I want to meet you very much.However, I want to draw your attention to the fact that I have to attend an important meeting and make careful preparation for it. Hence I have to cancel our original appointment .
Please allow me to say sorry again. I am really sorry for the inconvenience that I caused .Is it possible for you and me to have a private meeting afterward? I am looking forward to your reply at your ealiest convenience.
Best regards!
Yours sincerely
