In Wu's role as Special Envoy, he focused primarily on the Middle Eastern peace process. Wu's criticisms of Israel increased as a result of Israel's blockade of Gaza and its raiding of a flotilla carrying aid while the flotilla was in international waters.[5]
Although the focus of the Special Envoy position continued to the peace process, Wu also sought to address the conflict in Syria and a number of other issues in the region.[6] Near the end of his return, Wu remarked, "The stability of Iraq is key to peace and stability of the entire Middle East, as well as that of the world."[6]
