"This accord helps to definitively resolve the issue of Cuba's medium-term debt... Which has not been honoured since the 1980s," he said in a statement yesterday.
The cumulative interest amounting to USD 4 billion (3.6 billion euros) will be waived while the unpaid debt of USD 2.6 billion to France will be paid by Cuba over a period of 18 years, depending on its economic situation, he said.
"This arrangement offers a framework for a sustainable and definitive solution to the question of arrears due by the Republic of Cuba to the Group of the Creditors of Cuba covering a total stock of debt of USD 11.1 billion, including late interest, as of 31 October 2105," the Paris Club said in a separate statement.
Cuba owes money to Australia, Austria, Belgium, Canada, Denmark, Finland, France, Italy, Japan, the Netherlands, Spain, Sweden, Switzerland and the United Kingdom within the Paris Club.
President Raul Castro, who took over from his brother Fidel in 2006, began normalising relations with creditors in 2009 as part of an effort to revamp the island's Soviet-style economy.
The objective has been to generate confidence, gain access to credit and attract foreign investment.
