This paper examines the different regimes of insurer liability under concurrent causation in English law and Chinese law. The analysis shows that neither English law nor Chinese law is satisfactory in terms of the insurer's liability in such cases. It is argued that only one proximate cause should be identified among multiple causes except in the circumstance where an excluded risk and an insured risk concurrently and independently cause a loss of the subject matter insured. Under this exception, the liability in apportionment approach might be an appropriate solution to the question of the insurer's liability under concurrent causation. This approach, however, is not suggested for concurrent causation where an uninsured risk is one of the proximate causes.
