Abstract: The evolution of artificial intelligence has reshaped the essence of sovereignty across multiple dimensions, triggering extensive competition and cooperation within the realm of digital sovereignty. The United States leverages technological superiority to advance its ‘America First’ policy, while the European Union employs stringent regulatory frameworks to implement normative governance. China focuses on balancing the dual objectives of development and security. Within the global AI governance framework, digital inequalities frequently manifest as highly concentrated and monopolised data resources, uneven distribution of development opportunities, and intense competition for digital discourse power. To advance towards inclusive and shared global AI governance: On the dimension of equal rights, balancing data control rights with data development rights is essential, alongside establishing fairness review mechanisms for algorithms and computing power. On the dimension of equal opportunities, promoting the joint consultation, construction, and sharing of digital infrastructure is vital, alongside optimising technical assistance programmes and risk-sharing mechanisms. On the dimension of equal rules, advancing digital rule-making through multilateral consultation is necessary, alongside refining legal pathways for resolving conflicts of digital sovereignty.
