"All major official bilateral creditors, including China, should also deliver on our G20 commitments to provide debt relief to low income countries," Yellen said during a press conference.
Yellen said that debt issues are growing more acute for African countries and China is the main creditor country standing in the way of efforts to resolve excessive debt.
The United States and its G7 partners have had many discussions about what they can do to persuade China to cooperate on debt relief efforts.
World Bank President David Malpass said earlier this week that the bank is supporting the idea of comprehensive debt reduction, but he expressed concerns that the international community simply does not have the mechanism which would allow it to solve the debt issue.
Malpass stressed that the composition of debt has changed significantly over the years towards China and private sector creditors.
