China's efforts in conflict mediation are an important test of the durability of the principle of non-interference. By analysing the approaches and means of China's post-2014 mediation efforts in Afghanistan, this article finds that China's behaviour shows it engages in medium-level interference in domestic affairs, but mostly with the host government's concurrence. This is because of the two forms China's mediation takes. In a bilateral context, China's mediation takes the form of “incentivizing mediation,” in which its economic power, and its omnidirectional foreign policy, provide incentives or leverage for warring factions to come to the negotiation table, but which also lets the warring factions formulate their own roadmap to peace talks. In a multilateral context, China sometimes engages in “formulative mediation,” in which the mediators, not the disputing parties, formulate a roadmap to peace talks.
