Boston University's Global Development Policy Center published in September 2022 an analysis titled "China's Interest-Free Loans to Africa: Uses and Cancellations" by Jyhjong Hwang and Oyintarelado Moses.
China recently announced it would waive 23 interest-free loans with maturity by the end of 2021 for 17 African countries. The announcement of the cancellations did not elaborate on how much value they might represent, nor which 17 countries were involved. The Global Development Policy Center calculated that the value of the cancellations could vary from $45 million to $610 million. This range, even at the high end, constitutes a small portion of China's lending to Africa.
