In 2015, Chinese President Xi Jinping endorsed a new initiative, known as the Global Energy Interconnection (GEI), that could help solve humanity's pressing energy and climate dilemmas through the development of a global power grid. The GEI would connect remote renewable sources of energy to global consumption centers using ultra-high-voltage power transmission lines spanning continents and smart technologies. This way, peak demand for electricity in the evening in eastern China, for example, could be met using solar power at noon in central Asia, matching supply and demand across countries and continents more efficiently. On paper, the proposal presents many benefits. However, concerns about China's intentions and the political, security, and economic implications of a China-led GEI also exist. The GEI is reminiscent of China's similar controversial initiatives to connect with the rest of the world in such sectors as telecommunications, port infrastructure, and rail. In this report, RAND researchers set out to advance knowledge on the GEI and to demystify the potential global security implications associated with this important but poorly understood initiative.

Climate change is projected to affect the physical environment of the U.S. Central Command (CENTCOM) area of responsibility (AOR) significantly throughout the 21st century and could have consequences for security. How climate change might do this, and what these security consequences might be, are important issues for security planners. U.S. competitors and adversaries could have new opportunities to seek advantages relative to the United States. To understand how China, Russia, and Iran might exploit climate-related conflicts, the RAND Corporation hosted a two-day workshop that presented nine scenarios with different climate hazards and levels of conflict to a panel of 11 subject-matter experts. The experts were knowledgeable about the overall global strategy, interests, and capabilities of China, Russia, and Iran and were asked to assess how these countries would react to climate-related conflict. This report provides the results of that workshop. The purpose of this research is to support CENTCOM leadership and planners and their interagency partners to prepare for a future security environment that is affected by climate change. Understanding the frequency of future conflict in the AOR, as well as the evolution of threats under climate change, will enable the U.S. government to better prepare for this future. This report is the fourth in a series focused on climate change and the security environment.

Over the past decade, China has upended the world of development assistance, rapidly becoming the world's largest bilateral lender by channeling large sums of money into the developing world. As China's economic engagement in the developing world has grown, so too have U.S. and allied concerns that China is leveraging development assistance to assert Chinese influence, weaken the United States' relative position, and achieve Beijing's broader national security interests. In this report, the authors conduct a net assessment of U.S. and Chinese development assistance and cooperation. The authors describe each country's differing approaches to economic engagement with developing countries and conduct a data-driven comparison to identify strategic asymmetries that might present opportunities for the United States to better compete with China for relationships and influence in the developing world. The assessment reveals that Chinese economic engagement in the developing world should not be conceptualized as aid or assistance; this mischaracterization has potentially led to an overreliance on U.S. development tools as a primary response. Moreover, despite evidence of the short-term benefits that China might gain from its development financing, it is not clear whether these benefits are sustainable or effective over the long term when compared with the U.S. approach. Nevertheless, China's efforts — its heavy emphasis on energy and infrastructure projects, its approach to working through elite actors in developing countries, and its willing embrace of greater risk and reduced transparency — create challenges and opportunities for the United States as it looks to compete with China in the developing world.
