Over the last two decades, two drastic global transformations have reshaped the structure of international relations simultaneously, but in different contexts. On the one hand, the U.S. supremacy in the world politics and market has gradually declined, followed by the rise of China as a new economic hegemon. On the other hand, clean energy transitions became an urgent global concern and have shifted the global energy regime from fossil fuel-oriented to renewable energy- led. Although those two historical changes are contextually and categorically different, the recent economic dispute between China and the Western allies suggests two events are indispensable.
