Between 2009 and 2013，the discoveries of offshore natural gas fields in the Levant area ignited a gas revolution in Israel. The development of natural gas fields benefits Israeli economy in a direct way. The natural gas deposits guaranteed Israel’s energy security in some degree and made Israel a potential energy exporter. This newly discovered resource has offered a new opportunity for Israel to conduct regional diplomacy. Israel has faced many challenges when launching energy diplomacy，specifically disputes on domestic policy and maritime boundaries，interference from regional hotspots and security issues regionally. On the whole，energy diplomacy has a positive prospect which can help Israel stabilize its relations with the neighboring countries via energy cooperation. Progresses have been made under the present complicated situation in the East Mediterranean sea，though troubles will continue.
