Guenther reaffirmed his support for open trade and closer economic engagement with China, noting that regional cooperation serves as an important complement to federal-level relations.

KIEL, Germany, May 2 (Xinhua) -- Significant potential exists to deepen cooperation between the northern German state of Schleswig-Holstein and east China's Zhejiang Province, particularly in energy transition, hydrogen and advanced manufacturing, according to Daniel Guenther, minister president of Schleswig-Holstein.

His remarks come as the two regions mark 40 years of partnership, with both sides seeking to expand ties despite an increasingly complex geopolitical and trade environment.

"We are in good contact and have built a strong friendship over more than 40 years," Guenther said in a recent interview with Xinhua, highlighting long-standing cooperation in science, research and business.

Over the past three decades, Schleswig-Holstein has supported more than 200 local companies in exploring or establishing business in China, while around 70 firms from Zhejiang Province have set up operations in the German state.

Guenther reaffirmed his support for open trade and closer economic engagement with China, noting that regional cooperation serves as an important complement to federal-level relations.

Energy transition remains a central area of shared interest. Schleswig-Holstein has phased out nuclear power and is focusing entirely on renewable energy, with around 10 gigawatts of onshore wind capacity expected by 2026, alongside expanding solar generation.

"Renewables, hydrogen and energy policy are central topics for both sides," Guenther said. "We see that China have made great progress in these fields." He added that hydrogen could become a key area for future cooperation, offering strong potential for mutual learning and collaboration.

Beyond energy, universities also play a vital role in advancing cooperation. Schleswig-Holstein institutions maintain long-standing partnerships with Chinese counterparts, including collaboration between the University of Kiel and Zhejiang University, with plans to sign a new memorandum of understanding next year to deepen data exchange and research collaboration.

Guenther also pointed to the potential for cooperation in offshore wind projects and waste management, as well as battery manufacturing. He highlighted China's rapid development in areas such as electric vehicles and industrial innovation, noting that these align closely with the state's priorities. "These are fields where cooperation can go hand in hand," he said.
