Among the many issues surrounding China’s ongoing military modernization, perhaps none has been more dramatic than its nuclear weapons program. For decades, the Chinese government was content to maintain a comparatively small nuclear force. As recently as 2020, China’s arsenal was little changed from previous decades and amounted to some 220 weapons, around five to six percent of either the U.S. or Russian stockpiles of deployed and reserve warheads.

Whether they regard it as competitive, cooperative, or confrontational, virtually all observers agree that the U.S.-China relationship is consequential. From cyber norms and AI to military tensions in the Taiwan Strait and the global struggle to turn the tide on climate change, how Washington and Beijing manage their shared future will shape the globe for decades to come. Through research and relationship-building, the Center is dedicated to helping the U.S. and China collaborate and compete without conflict.

While China is building nuclear reactors faster than any other country in the world, major constraints may limit nuclear energy’s ability to grow to the scale of hundreds of gigawatts that would be required for it to play a major part in decarbonizing China’s energy system. This chapter explores the major constraints on, and risks of, large-scale nuclear energy growth in China, and how both new policies and new technologies might address them. It focuses particularly on the two biggest constraints – economics and siting. Substantial government policies to support nuclear power and advanced reactor systems designed to address some of the key constraints are both likely to be needed for nuclear to have a chance of playing a major role in decarbonizing China’s energy system; nuclear energy’s role may be bigger in the second half of this century than in the first half.

President-elect Joe Biden’s decision to create a new cabinet-level position for climate-related issues — and to choose so prominent a figure as former Secretary of State John Kerry to fill it — demonstrates Biden’s sincerity over putting climate at the very center of U.S. foreign policy. It is easy to understate the importance of this appointment, given the flurry of czars created by most new administrations.

The geopolitical and geo-economic forces wrought by the coronavirus pandemic, as examined previously in this series, are likely to slow the transition to a more sustainable global energy mix. Fortunately, the pandemic has also resulted in governments gaining vastly greater influence over whether this shift stalls or accelerates.

For most people, there was nothing to celebrate when the International Monetary Fund downgraded its outlook for global economic growth in June, anticipating a contraction of 4.9% for 2020. Yet for others, such as the small but persistent group of economists and others known as the “degrowth movement,” the Covid-induced economic slowdown has a silver lining.

The search for silver linings to the coronavirus pandemic has come up woefully short. But one hopeful — and much talked of — prospect is that the disruption will accelerate the global shift to a more sustainable energy future.

For months, the coronavirus has crawled across the globe. One person at a time, it has passed through millions, reaching every corner of the earth. And it has not only infected people, but every aspect of our human cultures. Policymakers and the public sector face their biggest test in generations—some say ever—as lives and livelihoods hang in a terrible, delicate balance. Facing health crises, economic collapse, social and political disruption, we try to take stock of what the pandemic has done and will do. We asked Harvard Kennedy School faculty, in fields ranging from climate change to international development, from democracy to big power relations, to tell us how this epochal event has changed the world.

The world is on the cusp of a geopolitical reset. The global pandemic could well undermine international institutions, reinforce nationalism and spur de-globalization. But far-sighted leadership could also rekindle cooperation, glimmers of which appeared in the G-20’s offer of debt relief for some of the world’s poorest countries, a joint plea from more than 200 former national leaders for a more coordinated pandemic response and an unprecedented multinational pact to arrest the crash in oil markets.  

Joseph Nye advises skepticism toward claims that the pandemic changes everything. China won't benefit, and the United States will remain preeminent.
