Chinese President Xi Jinping has returned to Beijing after wrapping up his four-nation Europe tour, which took him to the Netherlands, France, Germany and Belgium.

During the trip, the president attended the third Nuclear Security Summit in The Hague. He also visited the headquarters of the UN Educational, Scientific and Cultural Organization in Paris and the headquarters of the EU in Brussels. The two sides signed multi-billion dollar deals, with Europe pledging negotiations on a free trade agreement.

After giving a speech in Brussels, Xi met with workers at car manufacturer Volvo, which was acquired by China’s auto giant Geely in 2010. It capped the end of Xi’s four-nation tour in which he met with heads of state, including Germany’s Chancellor Angela Merkel and French President Francois Hollande.

In France, President Xi oversaw the signing of fifty deals worth twenty-five billion US dollars, including an order for seventy Airbus planes. In Germany, there were also multi-billion dollar agreements, including one to expand automaker Daimler’s presence in China.
