I am really sorry to inform you that Mr. Jung and I will be unable to attend the meeting scheduled on January 29th. This is because the approval of the budget has been being delayed by government = This is because the approval of the budget has been delayed by government and we are being asked to postpone any business trips until the approval has been completed.
I'll be in touch to try to work out a new time to visit. I apologize sincerely for the cancellation.

NOTE:

1st paragraph: Inform them why are you writing an e-mail to them.

2nd paragraph: Explain in details why the business trip was cancelled.

3rd paragraph: Tell them how you appreciate them and that you still look forward to see them soon.

Gratia, this could be your guide in making an e-mail to them. Write atleast 3 short paragraphs in your e-mail.
