The Japan International Cooperation Agency published on 14 December 2020 a study titled "Estimating China's Foreign Aid: 2019-2020 Preliminary Figures" by Naohiro Kitano and Yumiko Miyabayashi.
The study provides a wealth of information on China's global foreign assistance program from 2001 to 2020. Compared to the major bilateral donors--United States, Germany, and UK--China is a modest provider of overseas development assistance. The study does not break out China's aid figures by geographical region.
