Spanish Prime Minister Pedro Sánchez has made his fourth visit to China in three years, cementing a strategic partnership with Beijing at a time of mounting tension between Europe and the United States. President Xi Jinping welcomed the overture, viewing closer ties with Madrid as a foothold for broader European engagement amid China's own standoff with Washington. The two leaders aligned on calls for multilateralism and a multipolar world order, while also advancing economic cooperation in areas such as batteries and technology, though the deepening bilateral relationship raises questions about how far Spain can tilt toward Beijing without undermining European unity.
