Since the Kishida administration proposes the New Plan for a “Free and Open Indo-Pacific” in 2023，Japan’s Middle East diplomacy has become active in a sudden way. At the geo-economic level，Japan regards the Middle East as the main supply base for new energy in the future，and has launched in-depth cooperation in the field of new energy with the GCC countries headed by Saudi Arabia. At the geopolitical level，Japan has further enhanced its strategic partnership with major regional countries，established a regular strategic dialogue mechanism and developed a “mini-multilateralism” diplomatic model on this basis. Through this strategy，Japan has strengthened its export of the so-called “international order based on the rule of law” to the Middle East and expanded the scope of “like-minded countries”. However，the political ideas promoted by Japan have not withstood the test of geopolitical conflicts. In the process of responding to the Palestinian-Israeli conflict，the Kishida cabinet criticized Hamas’ actions on the one hand，but turned a blind eye to Israel’s violations of international law on the other. That pro-American and pro-Israel diplomatic posture abandons Japan’s long-proclaimed independence in Middle East diplomacy and will surely weaken its political influence in the Middle East.
