Chile acquired the pro tempore presidency of the organization on Wednesday, according to a statement issued by the Pacific Alliance.

The decision comes after Mexico declined to hand over the alliance’s rotating presidency to Peru, sparking a diplomatic row between the Latin American countries. Mexican President Andres Manuel Lopez Obrador has described the administration of Peruvian President Dina Boluarte as “spurious.”

The Pacific Alliance trade bloc is composed of Chile, Colombia, Mexico and Peru.

A meeting set to be held in Peru last December was postponed amid a political crisis in the South American country sparked by former president Pedro Castillo’s ousting and arrest for his attempt to illegally dissolve Congress.

“We have always recognized Peru’s right to exercise the pro tempore presidency… We have assumed the responsibility of acting as intermediaries to resolve this situation,” Chile’s Foreign Minister Alberto van Klaveren said in a press conference, adding his country will hold the presidency for a month.

“Authorities reaffirmed their commitment to the Pacific Alliance as a mechanism for political articulation, economic and commercial integration…, which seeks to advance progressively towards the free movement of goods, services, capital and people,” the statement added.
