AIDDATA published in March 2023 a report titled "China As an International Lender of Last Resort" by Sebastian Horn, Bradley C. Parks, Carmen M. Reinhart, and Christoph Trebesch.
China has emerged as a key lender of last resort for a growing number of developing countries. Most of these rescue loans between 2000 and 2021 have gone to low and middle-income countries with significant debts outstanding to Chinese banks. Of the 22 countries compiled by AIDDATA, only 7 (Angola, Egypt, Kenya, Nigeria, South Sudan, Sudan, and Tanzania) are in Africa and of those only Egypt and Nigeria were major recipients of Chinese bank bailouts. In total, the debtor countries received $240 billion in rescue lending--$170 billion mostly in renminbi extended by the People's Bank of China to central banks of countries in financial or macroeconomic distress and $70 billion from Chinese state-owned banks and commodity enterprises in mostly US dollar-denominated rescue loans.
The New York Times published on 27 March 2023 an article titled "After Doling Out Huge Loans, China Is Now Bailing Out Countries" by Keith Bradsher.
