China's rapid increase in food imports has repercussions for China's and global resources. This study reviews the recent literature on China's virtual water and land trade through food trade, presents updated results for 2000–2015, and makes projections for 2030. The results show that the increased imports of virtual water and land have significantly eased pressure on these resources in China. Soybean imports have been the main contributor towards China's domestic savings of virtual water and land. China's food trade has increasingly contributed towards global savings of virtual water and land. Our projections suggest that the trend in savings of domestic and global virtual water and land will continue, with significant variations due to changes in resource use efficiency.
