Analysts doubt that China can be a strategic challenge for multinational cooperation in the region. But the question is that is QUAD really the best platform for handling the growing Chinese capacity. Two members of the QUAD are too unreliable to serve this purpose, which are Australia and Japan. This leaves QUAD with two certain members India and America; whose growing strategic partnership is a threat to China anyways. There is no need for a QUAD for this purpose.
According to Regional Security Complex Theory, securitization is more intense between the countries inside of the regional security complex, patterned to the security interdependence of the region, a security cluster. Great outside power can penetrate it. RSCT leads to positive security interdependence by making shared security community or negative, including securitization, which leads to conflict formation. The defense pacts and agreements will undoubtedly lead to negative security interdependence by considering the region’s states’ dynamics.
However, since the past two decades, with the advent of a rising China and the increasingly securitized world, the political discourse in Japan with regards to its role in this new world has been increasingly contested, at times by highly opposite perspectives, on the nature of security and defence of modern Japan. Two recent strategic challenges underpin this highly contestable debate within Japan: China’s rise and the wavering of the American commitment to protect Japan from external belligerence in Trump’s era.
