The report you are reading is the result of a joint effort by the Shanghai Institutes for International Studies (SIIS) and the Center for International Security and Strategy (CISS) at Tsinghua University. We have tried to examine the root causes, impacts and implications of the Russia-Ukraine conflict from the perspectives of international order, China-US relations, China-EU relations, China-Russia relations, arms control and world economy. As Beijing- and Shanghai-based think tanks on international studies, we hope to present diversified but balanced voices to the pertinent discussions in China, and to provide a Chinese voice to readers outside of China.
