China and Portugal share a long history of trade and cultural exchange, dating back to the 16th century when Portuguese explorers first arrived in Asia. This relationship was marked by the establishment of Macau, a former Portuguese colony, which served as a significant trading post between Europe and Asia. Today, the two countries maintain diplomatic relations and engage in various economic partnerships. China is one of Portugal's largest trading partners in Asia, with cooperation in sectors like technology, renewable energy, and tourism, fostering mutual growth and understanding.
