Our world is going through a special period in history. It is faced with the combined impacts of the COVID-19 pandemic and major changes unseen in a century, and a heated contest between multilateralism and unilateralism. The global governance system is being readjusted in a profound way and international peace and security facing unprecedented challenges. It is in this context that President Xi Jinping, with the future of all humanity in mind, proposed the Global Security Initiative (GSI) for the first time at the opening ceremony of the Boao Forum for Asia Annual Conference 2022. This Initiative gives explicit answers to questions of our times such as what security concept the world needs and how countries can achieve common security, providing important guiding principles for resolving security dilemmas faced by humanity.
