While The Hereditary Grand Duke and Minister Krecké were in Shanghai they spent a considerable amount of time at the World Expo facilities. While they were there they visited the Saudi Pavilion, Dutch Pavilion, UK Pavilion, The Private Enterprises Pavilion and probably a dozen others. I did not check the websites of every pavilion for news and pictures.
Mr. and Mrs. Mao were the one millionth visitors to the Luxembourg Pavilion. They were fortunate enough that by a stroke of luck The Hereditary Grand Duke and Minister Krecké were in Shanghai. They received a commemorative coin and wine from The Grand Duchy.
This was an important working visit for for Luxembourg. The Hereditary Grand Duke and Minister Krecké made important contacts and participated in several events (noted in earlier entries).
