On March 9, 2022, Congjing Ran, Professor at the SIM, Wuhan University, published an article entitled withGlobal Situation and China's Response for the Governance of Data Sovereigntyat China Theory Network (http://www.ccpph.com.cn/).

In this article, the author pointed out that under the background of the vigorous development of the new generation of information technology represented by mobile Internet, cloud computing, big data, Internet of Things, artificial intelligence, etc., the jurisdiction and control of cross-border data gave birth to the claim of data sovereignty. Many countries and regions, such as the United States, the European Union and China, are actively deploying data sovereignty strategies. The differences between laws and regions have led to disputes over jurisdiction and data control rights. China should actively make suggestions for making international agreements, promote international cooperation in data sovereignty governance, improve its own data sovereignty strategy, and seek innovative development while defending national data sovereignty and ensuring national data security.

On July 2, 2021, the National Network Information Office published a notice to launch a network security review for Didi Chuxing. According to Article 9 of the Network Security Law, Didi Chuxing leaked geographical information abroad, which was suspected of threatening national security. As a result, Didi, a "Unicorn" company just listed on the US stock market, has been removed from the shelves by the regulatory authorities to stop the registration of new users. This incident has aroused widespread public concern about data sovereignty and data security. The new generation of information technology has spawned a large number of Chinese science and technology enterprises, some of which hold a large amount of user-sensitive data, and their active cross-border development in the international capital market may harm national data security and public interests. Data sovereignty is related to national interests and an important part of national sovereignty. China should put the protection of data security at the national strategic level, conform to the strict supervision trend of the global digital economy, and fully defend the national data sovereignty.

Internet services ignore the nature of national boundaries, eroding the traditional concepts of sovereignty and territorial jurisdiction, and geographical boundaries lose their meaning in the "cloud". Cloud service, as the future of global computing infrastructure, has a broad development prospect. In solving the complex jurisdictional problems caused by cloud computing, data sovereignty demands emerge at the historic moment. Internationally, data sovereignty refers to managing data in a way that conforms to the laws, practices and customs of the country where the data is located. It also means that the country adopts a series of methods to control the data generated in or through its own Internet infrastructure, and lets the data flow within the national jurisdiction. National data includes land, water, population, health, finance, crime and other information. With the explosive growth of Internet information, the management of national data becomes very important, and countries are looking for new and appropriate methods to ensure the security of national data.
