I am very pleased to have this opportunity to express how grateful I was for the warm hospitality you showed me during my last visit to Korea. The pleasant and enlightening conversation I was able to have with you during the luncheon is especially appreciated. Please allow me an opportunity of reciprocating in Seoul in the near future. Thank you again for all you’ve done to make my trip to Seoul very relaxing and enjoyable. I look forward to seeing you again soon.

I would like to thank you for the hospitality you extended on my recent visit to your country. The delightful and memorable lunch at your headquarters brought to mind again the close relationship between our two companies. I look forward to developing that relationship to the mutual benefit of our organizations.

Thanks and best regards,

David Kim
