I am writing to confirm our telephone conversation of Thursday, the 7th, about our visit to your company. Next Monday, Dec. 11, will be fine for us and we hope that it will suit you, too. My secretary, Miss Mary Brown, and Sales Manager, Mr. Zhang Ming, will be coming in the morning. It"s unfortunate that I will not be able to go with them.
Thanks again for giving us this opportunity to visit with you.
