PARIS/TOKYO/WASHINGTON (Reuters) - The United States, China and other G20 countries on Friday agreed for the first time on a common approach for restructuring government debt as the coronavirus crisis leaves some poorer nations at risk of default. The agreement came as Zambia said it would not pay an overdue Eurobond coupon by Friday’s deadline, putting it on track to become Africa’s first pandemic-era sovereign default. Citing the scale of the COVID-19 pandemic and “the significant debt vulnerabilities and deteriorating outlook in many low-income countries,” G20 finance officials agreed more help was needed than a current freeze in official debt payments that runs out at the end of June. Major creditors, including China, will be expected to follow the joint guidelines agreed by the G20, which lays out how debt deemed to be unsustainable can be reduced or rescheduled. International Monetary Fund Managing Director Kristalina Georgieva called the framework a historic achievement and said it should increase private sector participation and speed up resolution in cases where debts were unsustainable. “Let’s be very frank here. We are not out of the woods. This crisis is not over. We need further support through debt relief and through fresh financing,” she told G20 officials. African states alone face a financing gap of $345 billion through 2023, she has warned. Non-governmental groups said the accord should have gone further by including middle-income countries and forcing private investors to accept cancellations. A senior U.S. Treasury Department official said Washington was open to extending the joint framework to include middle-income countries and small island states, but that view was not shared by all G20 members at this stage. The official said the framework brought creditors such as China, India and Turkey into a coordinated debt restructuring process for the first time, but said Washington would be monitoring its implementation, especially by China, carefully. “I count on everyone’s constructive spirit to ensure swift and cooperative implementation of the common framework, with several countries already asking for debt treatments, in particular in Africa,” French Finance Bruno Le Maire told his G20 counterparts during an online meeting. China, which accounted for 63% of overall debt owed to G20 countries in 2019, has been reluctant to acknowledge the need for outright cancellation or reduction of debts. Estimates of total Chinese lending - which surged in the past 20 years - range from $350 billion to over $1 trillion, the U.S. official told reporters after Friday’s G20 meeting. Under the new framework, creditor countries will negotiate together with a debtor country, which will be expected to seek the same treatment terms from private sector creditors. The scheme borrows heavily from rules established by the Paris Club group of mostly wealthy nations established in 1956, which until now was the only joint forum for negotiating debt restructurings. The new framework aims “to facilitate timely and orderly debt treatment” for countries eligible for the debt payment freeze put in place in April, but which only included private sector creditors on a voluntary basis, the G20 statement said. “Debt transparency is extremely important,” Japanese Finance Minister Taro Aso told reporters after a G20 conference call. WAVE OF CRISES The new framework requires all public creditors to participate, after China was criticised by some G20 partners earlier for not including debt owed to its state-owned banks. Wary about debt write-offs, Beijing has defined the state-owned China Development Bank as a private institution, resisting calls for full participation in debt relief. Tim Jones, head of policy at Jubilee Debt Campaign, said in a statement that the G20 announcement allowed for, but discouraged outright debt cancellation, and did not create a mechanism to compel private sector participation. “This announcement falls far short of what is needed to tackle the wave of debt crises in poorer countries,” he said. Eric LeCompte, a United Nations adviser on debt and executive director of Jubilee USA Network, said inclusion of private sector creditors was a significant step, but criticised the G20 for failing to include middle-income countries. “Unfortunately, middle-income countries that will see some of the highest poverty increases due to the crisis, are excluded from this process, LeCompte said. The Paris Club, which is organised by the French Finance Ministry, and G20 countries had already agreed last month to extend this year’s debt freeze under which they deferred $5 billion in debt servicing to help the world’s poorest countries. G20 leaders are expected to endorse the common framework at a virtual summit meeting next week.
