Many countries have attempted to tap their diasporas by issuing bonds. This has particularly been the case in times of dire need (wars, pandemics, international sanctions, financial crises, and more). Ukraine is the most recent to have attempted to do this and failed. Other recent failures include Pakistan, India, Ethiopia and Greece, some of whom turned to bank deposit schemes when attempts to do full scale bond issuances did not succeed.
