The concept of Eurasia is connectivity between Europe and Asia. For the past decades, Eurasia has been redefined by two powerful countries China and India. China has designed its foreign policy to focus on establishing economic and cultural relationships with countries in Eurasia. China's important initiatives are "The New Silk Road" (also known as "One Belt One Road") and Maritime Silk Road. On the other hand, India has not yet seen a clear grand strategy in Eurasia at this moment. However, the Indian government shows a defensive tendency in the Indian Ocean in response to China's Marine time Silk Road policy and wants to cooperate sustainable investment with China. China and India have a matured nuclear arsenal from a nuclear approach and have been accustomed to minimizing nuclear deterrence. In recent years, China has a predominant military and economic advantage over India from nuclear weapon development and international trade perspectives. However, India owes a geographical advantage and multinational support; China needs to be concerned about its further maritime silk road development potential military collision. The oath of cooperation between two Asia superpowers becomes a blur and remains controversial.
