Russian President Dmitry Medvedev and Danish Queen Margrethe II will discuss trade and economic interaction on Tuesday, a Kremlin source reported. \"During a top-level meeting on September 6, considerable attention will be paid to discussion of urgent issues of trade, economic and investment cooperation. The Danish Queen is accompanied by an unprecedentedly large delegation - over 100 Danish businessmen,\" the source said. The Queen\'s visit to Russia starts on Tuesday. She will be accompanied by her spouse, Prince Consort Henri, their son Crown Prince Frederik, and a business delegation. This is Queen Margrethe\'s second visit to Russia. She visited Moscow and St. Petersburg in 1975. The visit comes after Medvedev\'s invitation to the royal family during his visit to Denmark in April 2010. Apart from the talks with Medvedev, the Queen will meet with Russian Prime Minister Vladimir Putin and take part in the opening ceremonies of the second Russian-Danish business forum, a Kremlin source said earlier. One of the key topics for negotiations will be cooperation in energy and especially the Nord Stream project. The Nord Stream pipeline will eventually pump 55 billion cubic meters of gas per year to Western Europe and will go through the territorial waters and exclusive economic zones of Finland, Sweden, Denmark and Germany. Russian-Danish trade in 2010 totaled $3.3 billion. Trade in the first half of 2011 grew 21.3% on the same period last year to $1.9 billion. Over 200 Danish companies operate in 25 Russian regions. Some 20% of them have already started their own production lines in the country.
