COPENHAGEN - Chinese and Danish companies signed deals worth more than $3?billion Friday as Chinese Vice-Premier Wang Qishan urged both sides to further enhance cooperation in the areas of trade, investment, finance, infrastructure, tourism and navigation.

Wang attended the signing ceremony of some 20 agreements on cooperation between Chinese and Danish companies. The value of the cooperative projects totalled $3.35 billion.

Speaking at the Chinese-Danish Conference on Business and Trade held before the signing ceremony, Wang said the companies of the two countries should not only jointly expand market in each country, but also explore the international market.

Danish Crown Prince Frederick and Deputy Prime Minister Margrethe Vestager also witnessed the signing ceremony and attended the conference.

Wang said Chinese and Danish companies should continuously turn the prospect of cooperation into reality.

Wang is among the entourage of Chinese President Hu Jintao who is paying a state visit to Denmark.

Wang said Hu's visit, which is the first one by the head of state of China in the past 62 years, is a milestone in bilateral relations. He said Hu's visit will greatly advance the development of the comprehensive strategic partnership between the two countries and bring about fresh opportunities for cooperation between their companies.

Wang noted that in the past decade, two-way trade has been growing at an annual rate of 22 percent. The trade volume rose to nearly ten billion U.S. dollars last year.
