China and Argentina have formalized the expansion of a currency swap deal, allowing the South American country to increase its depleted foreign currency reserves, the Argentine central bank said on Sunday.
Argentina's government needs to rebuild reserves to cover trade costs and future debt repayments, and more reserves are a key objective of a major debt deal with the International Monetary Fund.
Argentine President Alberto Fernandez announced the deal in November last year.
The heads of the Argentine and Chinese central banks "confirmed that the deal for the swap of currencies between both institutions has been activated and committed to deepening the use of (Chinese yuan) in the Argentine market," Argentine's central bank said in a statement.
China is Argentina's second biggest trade partner, after Brazil, and the second most important destination for Argentine exports.
"The swap comprises the exchange of currency for reinforcement of international reserves of 130 billion yuan ($19 billion) and a special activation of 35 billion yuan to compensate operations on the foreign exchange market," the statement said.
