Ecuadorian President Daniel Noboa has offered to cancel tariffs following a conversation with a right-wing Colombian presidential candidate ahead of Colombia's election on Sunday.

The tariff pledge has prompted accusations that Ecuador is interfering in Colombia's electoral process through economic incentives tied to the outcome of the vote.

The timing of Noboa's announcement, coming just days before Colombian voters head to the polls, has raised questions about the appropriateness of such commitments during an active election campaign.

Details about which specific tariffs would be affected or the scope of the proposed cancellations were not immediately available. The identity of the Colombian presidential candidate involved in the discussion was also not specified in initial reports.

Colombian elections are scheduled for Sunday, with multiple candidates competing for the presidency in what observers describe as a closely contested race.
