If one takes Marco Rubio’s recent remarks on the end of unipolarity at face value, one could be mistaken for believing that the question of a multipolar world is settled. On the contrary, Rubio’s ruminations, together with remarks from members of the new Trump Administration, including the President himself, buttressed with decisions made in the first few weeks of the new administration, suggest that the issue of multipolarity is very much in question.

Three major conferences held in Europe — the Davos Forum, the Artificial Intelligence Action Summit and the Munich Security Conference — underscored the defining feature of the current international landscape: It’s a complex and evolving mix of cooperation and competition.

Ukraine crisis lingers as the transatlantic alliance faces an uncertain future. Meanwhile, the international order is undergoing a profound restructuring as the sand shifts under traditional commitments by the United States and as Europe seeks greater autonomy.

The United States needs to recognize that global hegemony is not sustainable. It should stop clinging to the postwar structure, with itself in the dominant position, and should learn to play a more ecumenical role in a multipolar world.

The Indo-Pacific Economic Framework adopted by the United States last year has led to a shift in the way East Asian countries perceive their relations with the world’s two great powers. The notion of reliance on China for economics and on the U.S. for security has begun to tilt westward.

Weaponized interdependence, through which powerful states leverage their position in the global network to achieve strategic goals, is increasingly relevant in the U.S.-China relationship. The U.S. uses its market power and network of alliances to exclude adversaries from the global dollar-dominated system, but this approach has also accelerated the process of global multipolarity and created opportunities for other countries to create alternative ecosystems.

Chinese president’s trip was a positive, good-faith effort to defuse the crisis in Ukraine and prevent bloc confrontations. China wants to maintain international peace and stability while seeking to open up broad new prospects for relations between major powers.

Positive trade mechanisms have emerged. China remains committed to developing its relationship with the U.S. The recent tension over Taiwan was controlled. Such things and others are a basis for optimism, not despair.

The Russo-Ukraine conflict has raged on and looks to continue into the near future, straining relations in Europe. The ripple effects of military conflict involving a pronounced foe of the United States has created an even more tense climate on a global stage that already sees U.S.-China relations declining at an alarming rate.

Major-country relations are changing dramatically. Chinese academics and political leaders should conduct an in-depth analysis of what China faces. The United States has already started a new Cold War in regional and global industrial chains.
