It is generally believed that under the leadership of Modi，India has entered an era of “strong government” with increasingly progressive foreign policies，stronger intent to compete with China for the global great power status and more salient “strong government” mentality in foreign policy. This article discusses the causes of the “strong government” mentality of India and its possible effect on Sino-Indian relation，focusing on the “strong” mentality of India and its effect on the Sino-Indian border issue and the “Belt and Road”. This article argues that the strong mentality of Modi does not derive from the change in the power of India，not even the change in the comparative power of India，but the change in the psychological level when India promotes its foreign policies. Based on the reality of diplomacy，India is still a follower of the international systems but not the creator of orders. The actual international status of India is not upgraded with Modi assuming power. What is upgraded is just India’s confidence and the expectation of some Western countries on India. When dealing with the relation with India，china must consider the long-term possibility of India’s development and the structure factors which will determine the direction of its development，instead of only focusing on its dazzling performance in the short run，esp. the so called impression of strong government given by India.
