Sample:
Dear Anna,
Please allow me to take this opportunity to introduce a visiting scholar, George Martin, from University of California at Berkeley. He will be a member of our Program of AsiaPacific Economy for nine months.
George is an enthusiastic and enterprising scholar. He has done various researches on American and Asian economies for more than ten years. I am sure that his participation will do a lot of help to our recent research.
George will be arriving here on next Friday and he will soon go to visit you after arrival. You can introduce the overall development of our program to him, and then explore the details of cooperation.
Sincerely yours,
Li Ming
