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
economic and trade
 relations and bring our business people together.

I am looking forward 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,

(Signed)

Mr.___ Minister of Economic Cooperation
