Zheng He worked untiringly to develop Sino-foreign relations throughout the course of his career. His initial voyages succeeded in establishing an initial reputation, while the later voyages concentrated on impressing the world with China's magnificent material and spiritual civilization. It was hoped that by expanding diplomatic and trade relations via the new maritime routes, foreign countries would come to better understand China and establish closer economic ties. Such exchange would not only benefit both sides, but was necessary for China's continued growth. Zheng He's western voyages not only established trade between China and the countries of Asia and Africa, but successfully opened the new maritime Silk Road.
