Gopnick does mention European contact with Chinese philosophy and theology in the paper that hownottowrite linked, however this is dismissed as a contact point for Buddhism: "European scholars in the Chinese court focused on the elite Confucian and Taoist traditions." It is my understanding that Leibniz was mostly exposed to the Confucian tradition, his correspondences with Joachim Bouvet on this topic are mentioned in the paper.
