Dear Minister,
I am writing this letter to thank you for you warm hospitality accorded to me and my delegation during our recent visit to your beautiful country. I would also like to thank you for your interesting discussion with me which I have found very informative and useful.
During the entire visit, my delegation and I were overwhelmed by the enthusiasm expressed by your business representatives on cooperation with China. I sincerely hope we could have more exchanges like this one when we would be able to continue our interesting discussion on possible ways to expand our bilateral ecomomic and trade relations and bring our business people together.
I am lookingforward to your early visit to China when I will be able to pay back some of the hospitality I received during my memorable stay in yur beautiful country. With kind personal regards,
Faithfully yours,
Mary
