During the reign of Tamim，Qatar's diplomatic strategy had the connotation of “pluralism” and “independence”，including the regional strategy which broke the diplomatic framework of the GCC and moved towards the Middle East to join the world，including the economic strategy that strengthened energy diplomacy，balanced relations with major middle eastern countries，and strengthened cooperation with major world powers in the military field. The pluralistic and independent diplomatic strategy is a diplomatic system constructed by Qatar to safeguard its core interests，driven by domestic liberalization and reform，stimulated by pressure from Gulf powers and manipulated by world powers behind the scenes. The implementation of Qatar's pluralism and independent diplomatic strategy is likely to lead to the division of the GCC. The further development of the strategy undoubtedly will face many difficulties and obstacles，but the core of the strategy is the need for internal development of Qatar and the direction of Qatar's diplomacy，which will not be easily changed.
