A UN committee on Tuesday unanimously adopted a "historic" report that establishes nine principles for restructuring sovereign debt, the committee's chair Sacha Llorenti of Bolivia told reporters.

"This constitutes a historic moment when it comes to resolving the issues of foreign debt restructuring," Llorenti, who chairs the UN ad hoc committee on sovereign debt restructuring processes, said at a press conference here.

The principles included the right of the sovereign state to restructure their debt; good faith; transparency; impartiality; equitable treatment; legitimacy; sustainability; and majority restructuring.

However, Llorenti noted that 11 countries had not supported the establishment of the committee in December 2014 and that these same countries had a greater share of the votes at the International Monetary Fund, which currently controls debt sovereignty issues.

US Economist Joseph Stiglitz told the committee in a keynote address that the International Monetary Fund (IMF) control over debt restructuring didn't make sense because the IMF is an institution of creditors.

"The IMF is an institution of creditors, you would not ask Citibank to design the bankruptcy law in the United States," he said, referring to a major US bank. "We need a fair bankruptcy law an efficient bankruptcy law and the bankruptcy laws that come out of creditors are neither fair nor efficient."

Stiglitz also pointed to Greece and Argentina as recent examples of countries that have suffered because of inadequate frameworks for debt restructuring.

"In the absence of an adequate framework for debt restructuring economies often go into deep recession -- depressions as we see today in Greece -- as we saw in Argentina," he said.

Richard Kozul-Wright, strategies director of the United Nations Conference on Trade and Development (UNCTAD), told the press here that part of the problem was that the same rules and practices that had been created at national levels to manage debts, did not exist at the international level.

"At the international level where we have also high levels of indebtedness there is no equivalent of national bankruptcy laws and it's a major gap in the international system," he said.

Kozul-Wright described the committee's decision as an important step that UNCTAD had been advocating for the past 30 years.

"This is a very important first stage in moving towards a more rational way of handling sovereign debt crises from the very fragmented unfair system that we have," he said.
