In 2021, oil and gas fields were widely distributed, the number of non-producing oil and gas fields was large;the whole oil and gas remaining recoverable reserves declined slightly, unconventional oil and gas remaining recoverable reserves dropped significantly;the overall oil and gas production continuously increased, the outputs of key resource-host countries kept year-on-year growth;undeveloped oilfields had abundant reserves and great development potential. Combined with global oil and gas geopolitics, oil and gas industry development trends, oil and gas investment intensity, and the tracking and judgment of hotspot fields, the major trends of global oil and gas development in 2021 are summarized. On this basis, the four aspects of enlightenment and suggestions for international oil and gas cooperation and development strategies are put forward: attach great importance to the obligation of marine abandonment to ensure high-quality and long-term benefit development of offshore oil and gas;adhere to the principle of not going to dangerous and chaotic places, strengthen the concentration of oil and gas assets, and establish multi stable supply bases;based on the multi-scenario demand of natural gas, realize the transformation from integrated collaboration to full oil and gas industry chain development;increase the acquisition of high-quality large-scale assets, and pay attention to the continuous optimization of the shareholding ratio of projects at different stages.展开更多

Global issues, vital to the survival of mankind, rise to the top agenda of national governments. The epicenter of global power is shifting from U.S. and Europe to the rest of the regions. The global "political excitement and zeal" is rolling on. All exact more on the competence of global governance. The current international multilateral mechanisms are in "competence deficit", worsening either in terms of adequacy, validity or legitimacy. The call for the reform of it is ever soaring. China by the way is at once engaging in the multilateral diplomacy transforming the international system and facing the growing pressure of assuming "leadership" and "international responsibility". China needs to continuously adapt to the changed national identity in the multilateral diplomacy, to reconcile the multilateral mechanisms that deal with regions and domains in China's strategic planning and laying-out, to organically associate the short-term and long-term goals and to upgrade the concept of harmonious world in the practice of multilateral diplomacy.展开更多
