BEIJING (AP) — German Chancellor Olaf Scholz arrived in China on Sunday on a visit focused on the increasingly tense economic relationship between the sides and differences over Russia’s invasion of Ukraine.

Scholz’s first destination was the industrial hub of Chongqing, where he and his delegation of ministers and business leaders were to visit a partially German-funded company and other sites in the vast city, which is a production base for China’s auto and other industries.

Scholz is also scheduled to visit the financial hub of Shanghai during his three-day visit, before traveling to the capital, Beijing, to meet with Chinese leader Xi Jinping and Premier Li Qiang.

German companies such as BMW and Volkswagen are highly reliant on the Chinese market, even as Beijing’s support for Russia creates frictions with the West.

Germany’s economy has benefited from China’s demand for investment and manufactured items from cars to chemicals, but those ties have frayed amid increasing competition from Chinese companies and tightened regulations. Political interference has also been blamed for a sharp drop in foreign investment.
