This represents a significant adjustment in US regional policies. An important power in the Indian Ocean region, India is perceived as key to the successful implementation of this Indo-Pacific strategy. Generally speaking, the current Indian government and strategy circle actively support the upgrading of the"Indo-Pacific"concept from a geographical and academic term to a US vision for foreign strategies, anticipating that India could garner significant strategic benefits from it. Given this, New Delhi will continually adapt its foreign policies to the US Indo-Pacific strategy and may even direct the development of the strategy to counter the Belt and Road Initiative, work with other nations to balance China's influence and finally make the rise of India as a great power a reality. Nonetheless, the Indo-pacific strategy is in its early stages, and the content is not completely pro-India currently. On top of this India is still skeptical of the US and will proceed cautiously, leaving room for maneuver in the future,fully tapping into the benefits of the Indo-Pacific strategy and avoiding direct confrontation with China.展开更多
