Global Science & the U.S.-China Rivalry

Nowadays, China, the U.S., and their scientific collaboration have become cornerstones of the production of scientific research globally. In addition to their respective domestic research enterprise, the U.S.-China partnership takes a leading role in many of the international scientific projects. The massive number of Chinese students and scholars formed and trained in the U.S. is another sign of the importance of this partnership. With the rise of China, however, the relationship between the two countries degraded and became defined more and more by a so-called great power competition. This rivalry is now interfering with their scientific partnership and endangers the whole international scientific endeavor by imposing restrictions on exchanges, collaboration and funding.  I am interested in shedding light to the real motives that drive these restrictive policies, to their implementation, to the consequences that they have on U.S.-China scientific collaboration and global science, and to how they might reshape whole industrial and research sectors around the world.

As the two major global scientific actors, the international community needs the joint participation of China and the U.S. to tackle global issues such as global warming, pandemics, and nuclear arms control. By restricting the U.S.-China scientific partnership, the current rivalry is also endangering global science. In this work, I expose the importance of the U.S.-China scientific partnership, how recent restrictions are implemented on both sides, and I make policy suggestions that could help preserve global science.
