Xi prepares to clinch deals on European trip(2)

Apart from Berlin, Xi will also visit Duesseldorf.

Leaders from the two sides will sign cooperation documents covering sectors including industry, aerospace, science and technology as well as culture and education.

Jia Xiudong, a researcher at the China Institute of International Studies, said that based on frequent mutual visits by high-ranking leaders from both China and Germany and constantly increasing bilateral trade, ties between the two nations "have kicked into high gear in the past decade".

"Economic ties will continue to be the engine for ties between Beijing and Berlin in the future," Jia added.

Xi will end his European visit in Belgium, where he will meet King Philippe, Prime Minister Elio Di Rupo and parliamentary officials and sign cooperation agreements covering trade, science and technology, and education.

In Belgium, Xi will also visit the European Union headquarters and set the direction for future Sino-EU relations when he meets President of the European Council Herman Van Rompuy, European Parliament President Martin Schulz and European Commission President Jose Manuel Barroso.

According to China's official statistics, bilateral trade between the country and the EU reached $559 billion in 2013. The EU has been China's largest trade partner for 10 years and China has been the 28-member bloc's second-largest trade partner for 11 years.

Zhao Junjie, a researcher of European studies at the Chinese Academy of Social Sciences, said: "The development of China-Europe ties has shown favorable momentum. This visit will inject new energy to the long-term stable development of these ties."

In November, China and the EU launched negotiations on an unprecedented bilateral investment treaty during the 16th China-EU Summit. Zhao said the start of talks on the treaty represented an important and positive change of approach to bilateral relations. The treaty will offer a good opportunity for China to attain international standards in trading and investment and to become more involved in the global economy.

Chen Mingming, former Chinese ambassador to Sweden, told China Daily, "The treaty can contribute to avoiding trading disputes and protectionism."

China and the EU have clashed over trade issues, principally over EU accusations in the first half of 2013 that Chinese companies were selling solar panels in the bloc below cost.

Zhao said leaders from both sides should show more respect and tolerance of each other's differences and develop a cooperation mechanism.
