Abstract：Strengthened interaction between the Indian Ocean and the Pacific gives rise to the emergence of the Indopacific region, with its core lies in the rapid development of China and India. The formation of the Indopacific region provides a realistic basis for the construction of the Indopacific system. The construction of the Indopacific system is faced with two strategic choices: to be a governance system responding to public issues in the Indopacific region or an alliance system aiming to contain Chinas increasing regional influence. So for, Indopacific system remains plastic since the strategic considerations of Australia and India diverge from that of the US and Japan. However, the Indopacific regions strategic framework is very much likely to develop into the alliance system as a result of changes in SinoUS strategic relations and Australias policies on China.
