This article shows how China’s rise has radically altered the politics of one of the most prominent and controversial issues in the global trading system: agriculture subsidies. Agriculture subsidies depress global prices and undermine the competitiveness and livelihoods of poor farmers, and therefore have been long seen as a symbol of the injustice of the trading system. The issue has traditionally been understood in North-South terms, with developed countries seen as the perpetrators of harm and developing countries as innocent victims. In this article, however, I challenge this prevailing conception of the agricultural subsidies issue, arguing that it is now out of date and no longer corresponds with the emerging reality. A momentous but underappreciated change has taken place, largely beneath the radar of IPE scholarship: China has emerged as the world’s largest subsidizer, profoundly transforming the global politics of agricultural subsidies. From a North-South battle, WTO negotiations on agricultural subsidies are now primarily centered on a conflict between the US and China. While reducing subsidies remains a pressing concern for developing countries, efforts to negotiate new and strengthened disciplines at the WTO have been thwarted by an impasse between the two dominant powers.
