Key Points
— Colombia imposed reciprocal 100% tariffs on Ecuadorian imports on Friday, matching Ecuador’s escalation and making the trade war fully symmetric. Commerce Minister Diana Morales declared: “We have exhausted all diplomatic efforts.”
— CAN-mediated negotiations have been formally suspended. Canciller Villavicencio confirmed Colombia is “already requesting entry into Mercosur” as a full member—a move that would reshape South America’s trade architecture if it survives the change of government in August.
— Bilateral trade had already collapsed 66.8% at the 30% tariff level. At mutual 100%, the $2.8 billion annual commerce between the two countries has effectively ceased. Both ambassadors have been recalled. No mediation channel remains open.
In January it was a “security tariff.” By April it is mutual economic excommunication. Two Andean neighbors that share a 600-kilometer border, $2.8 billion in annual trade, and a war against the same cartels have chosen to punish each other rather than cooperate.
Colombia’s Ministry of Commerce announced on Friday that it had imposed 100% tariffs on all Ecuadorian imports, matching the duty Ecuador imposed on Colombian goods one day earlier, as reported by ATB Digital, Diario Las Américas, El Colombiano, and CNN en Español. Commerce Minister Diana Morales said the government had “exhausted all diplomatic efforts” before retaliating. The move makes the trade war fully symmetric for the first time: both countries now charge 100% on every product crossing their shared border. At the 30% tariff level imposed in January, Ecuadorian imports from Colombia had already collapsed 66.8%. At bilateral 100%, formal trade between the two countries effectively ceases.
No Mediation, No Diplomats, No Channel
Every formal line of communication between the two governments is now severed or suspended. Ecuador recalled its ambassador from Bogotá on Wednesday after Petro called imprisoned ex-Vice President Jorge Glas a “political prisoner”—a reference to the 2024 military raid on Mexico’s embassy in Quito that triggered an international crisis. Petro ordered his own ambassador home on Thursday and announced the next cabinet meeting would be held “at a point on the border.” CAN-mediated negotiations, which had been underway since March, were formally suspended. Ecuadorian Canciller Gabriela Sommerfeld told reporters the talks would remain frozen “until the appropriate environment is found.” No date was set. No intermediary was proposed.
The Mercosur Gambit
Canciller Yolanda Villavicencio confirmed on X that Colombia was “already requesting entry into Mercosur” as a full member, upgrading from its current associate status. If completed, the accession would add a 52-million-person market—the fourth-largest economy in South America—to a bloc currently comprising Brazil, Argentina, Paraguay, Uruguay, and Bolivia. It would also reduce the CAN to three members (Ecuador, Peru, Bolivia), potentially rendering the 57-year-old Andean pact irrelevant as a trade instrument. Petro framed the shift as strategic: “The canciller must begin the process with Mercosur as full members and direct us toward the Caribbean and Central America with greater force.”
The question is whether the gambit outlasts Petro. Colombia’s presidential election is in October, and Petro cannot run again. His leftist coalition candidate, Iván Cepeda, is not guaranteed to continue the Mercosur pivot. A center-right successor could reverse course, rejoin CAN negotiations, and restore the Ecuadorian relationship. The Comité Empresarial Ecuatoriano has called on both presidents to pursue “urgent dialogue as the only mechanism for resolution,” and Colombian business leaders have echoed the message. For now, neither government is listening.
Who Benefits, Who Pays
Ecuador’s Noboa claims vindication: he told reporters that since imposing the initial tariffs, violent deaths along the northern frontier have fallen 33%. He framed the 100% tariff as the cost of security in a border region dominated by drug cartels, illegal mining, and human trafficking, arguing Ecuador must spend $400 million per year to secure a frontier Colombia fails to patrol. The trade data tells a more complex story. For the first time in 25 years, the bilateral balance favors Ecuador ($62.9 million in Q1 2026) simply because Ecuadorian imports from Colombia have collapsed faster than the reverse. Colombia sells Ecuador mainly electricity, pharmaceuticals, vehicles, cosmetics, and plastics; Ecuador sells Colombia vegetable oils, tuna, minerals, and metals. Both product baskets are now priced out of each other’s markets. The smuggling networks that originally triggered this crisis—the same cartels that both governments claim to be fighting—remain the primary beneficiaries of every formal trade channel that closes. They operate without tariffs, without ambassadors, and without CAN mediation. They will be the last to feel the pain.
