After entering the era of Xi Jinping administration, China's 3.0 version foreign policy has been continuously developing in practice. Especially since 2017, China's 3.0 version foreign policy continued to have new changes as follows: First, it emphasized the “Foreign Policy of Neighboring Countries” and put the “Belt and Road Initiative” into the Communist Party Constitution. Second, added “Adhering to the Path of Peaceful Development”, “Adhering to the Win-Win Strategy of Opening up” and “Promoting the Building of a Community with a Shared Future for Mankind” to China Constitution. Other than that, “New Concept of Asia Security” and “Bottom-line Thinking” also gradually are implemented in China's diplomatic practice. In the volatile international society, there have been upstreams against globalization and regional integration, of which Modi administration is one example. Modi pushed for Hindu nationalism, which not only set off drastically religious nationalism trend in the domestic, but also led to spillover into the international community. The Indian military respectively crossed the border into China and caused the Dong Lang Issue and the Galvan Valley Conflict. These issues seriously affected the relations between the two countries and challenged the implementation of China 3.0 version foreign policy. This paper focuses on how the important concepts in the 3.0 foreign policy were applied to the diplomatic practice against India, and how China avoided the escalation of the situation. From the paper, we can find that China maintained a high degree of restraint and insisted on solving the problem through negotiation and consultation in the Dong Lang Issue. In the interlude between the two issues, China actively promoted the interaction between two leaders and sought to build a momentum of peace and mutual benefit. In the Galvan Valley Conflict period, China stuck to the “Bottom-line Thinking” at well as adhered to the “Path of Peaceful Development”. China in the future will still need to adhere to these 3.0 version foreign concepts-- “the Great Power Relations”, “Bottom-line Thinking” and “Amity, Sincerity, Mutual Benefit and Inclusiveness in China's Neighborhood Diplomacy”. China will safeguard its core interests and maintain a good foreign environment in order to contribute to peace and development of the international society.
