　　Thank you, Mr. xxx. I feel deeply indebted to you and I really don't know how to thank you enough for your help.It's a great honor to be following in your footsteps as Overseas Sales Manager.

　　To be honest, this promotion came as quite a surprise. I'd like to think it's mainly a recognition of the teamwork, above and beyond the call of duty, in my department. On that same note, I'd like to thank all my colleagues in the company for their enthusiasm and hard work. Due to their efforts, we've really gotten some overseas projects off the ground for Action.

　　Looking to the future, I'd still like to maintain contact with everyone, even though I'll be working at the senior level. Well, what I'm trying to say is I won't let this step-up go to my head. My door will always be open. Thank you again.
