Despite the severity of the incident, Colombia and Peru have indicated a willingness to address it through diplomacy

 An incident on April 12, 2026, has reignited diplomatic and security tensions in the Amazon border region between Colombia and Peru, following an exchange of gunfire between a Colombian civilian vessel and the Marina de Guerra del Perú, a Peruvian Navy River unit, on the Putumayo River. The incident left one Colombian citizen dead and one person injured on each side.

The episode occurred near Marandúa (Amazonas, Colombia), across from the Peruvian town of El Estrecho. According to Colombia’s Defense Minister, Pedro Sánchez, the fatal victim was identified “as José Miguel Gutiérrez Baquero, owner of the cargo vessel involved in the incident, and one of his sons was injured,” while two other crew members were detained by Peruvian authorities.

Conflicting accounts of the operation

According to the Peruvian government statement, “the incident occurred during a patrol operation aimed at securing the electoral process,” previously coordinated between the two countries. Authorities said two Navy speedboats requested that the Colombian vessel stop for identification.

Peru’s Ministry of Foreign Affairs, which is leading the process, said that “the Colombian vessel refused to comply with the control order and opened fire on two Peruvian Navy units, which returned fire.” As a result, “a member of the Peruvian Navy was also injured, although he is out of danger.”

Colombian authorities, led by the Foreign Ministry, have requested a full clarification of the events and verification of the circumstances surrounding the exchange of gunfire.

Diplomatic channels activated

Following the incident, the governments of Colombia and Peru activated diplomatic and military channels. Colombia’s defense minister said that “preliminary measures were agreed, including prioritizing medical attention for the injured, facilitating the work of judicial authorities, and establishing a binational commission to investigate what happened.”

Colombia’s Foreign Ministry formally requested clarification of “the circumstances of time, mode and place” of the attack, while the Peruvian government expressed its “willingness to cooperate and maintain border coordination mechanisms.”

The detained individuals “remain in the custody of the Fiscalía Provincial Mixta de Putumayo, with access to consular assistance and due process guarantees.”

So far, no final responsibilities have been determined, and both countries agree on the need for a thorough investigation. Both governments said the issue will be addressed at the next High-Level Mechanism on Security and Judicial Cooperation meeting, scheduled for May 2026 in Bogotá.

Context of prior tensions

The incident comes amid sensitive bilateral relations. In recent months, Colombia and Peru have had disagreements over territorial issues in the Amazon, particularly regarding Santa Rosa de Loreto island.

The dispute dates back to August 5, 2025, when President Gustavo Petro said on X that the “government of Peru has taken over territory that belongs to Colombia” and alleged a “violation of the Rio de Janeiro Protocol, which defines the boundaries between the two countries.”

“The Rio de Janeiro Protocol established that the border is the deepest channel of the Amazon River and that any dispute must be resolved between the parties,” Petro said, referring to the emergence of new river islands “north of the current deepest channel,” which, according to his position, should belong to Colombia.

In response, Peru’s Foreign Ministry expressed its “strongest and most forceful protest,” stating that the island, home to about 3,000 residents, mostly Peruvians, is part of its territory and is key to regional river trade.

Tensions escalated days later when then-presidential pre-candidate Daniel Quintero traveled to the island and raised a Colombian flag during a campaign event broadcast on social media, saying: “I will not allow them to take the Amazon from us. Santa Rosa is Colombia.”

The Peruvian government described the act as an “unnecessary action” that “distracts from the cooperation efforts that Peru and Colombia must prioritize to jointly address urgent challenges.”

Colombia’s Defense Ministry detailed a plan to bolster security along the Ecuador border

Colombia’s government has announced a package of measures to strengthen security in municipalities along the border with Ecuador, amid escalating tensions between the two countries over security and trade issues.

According to a statement released by the presidency, the actions include “the deployment of 200 additional National Police officers and 270 soldiers, as well as enhanced maritime and riverine capabilities for territorial control and the fight against drug trafficking.”

The plan also includes technical support for surveillance systems, the deployment of two armored platoons to ensure troop mobility, and meetings aimed at strengthening joint operations by security forces and control at border crossings.

Defense Minister Pedro Sánchez announced the measures, stating that “we will not allow criminal groups seeking to profit from illegal activities such as drug trafficking, illegal mining, extortion and smuggling to affect security indicators.”

He added that security forces have already seized 2.4 tons of drugs and remain deployed in the region “to protect our seas and critically disrupt drug trafficking.”

Context: security and trade tensions

The measures come days before Ecuador’s tariff increase takes effect, raising the so-called “security tariff” on Colombian goods from 50% to 100% starting May 1, 2026.

Ecuadorian President Daniel Noboa told Revista Semana magazine that the decision is not part of a “trade war” with Colombia but rather reflects the costs of reinforcing border security. “We have to spend twice as much, and it costs $400 million USD more per year to keep our armed forces deployed at the border,” he said.

For its part, Colombia’s government has rejected claims of insufficient action on border security. Minister of Commerce, Industry and Tourism Diana Marcela Morales Rojas said Colombia has kept diplomatic channels open.

“We have exhausted all diplomatic efforts and maintained open dialogue channels with the Government of Ecuador, seeking a solution that benefits both countries, businesses and, above all, communities on both sides of the border. However, we have not received a positive response,” she said in a statement.

At the same time, Colombia is evaluating its tariff response. Although President Gustavo Petro previously said he would not impose 100% tariffs on Ecuador, a draft update to Decree 170 of 2026 has recently emerged proposing differentiated tariffs of 35%, 50% and 75% on imports from the neighboring country. So far, the proposal has not been signed or officially published.

Ecuador has sharply increased tariffs on Colombian crude oil transported through its pipeline system, deepening a trade and energy dispute between the two Andean neighbours that has already disrupted electricity exports and bilateral commerce.

Ecuador said on Tuesday it had raised the tariff paid by Colombia for each barrel of oil transported through the state-owned Trans-Ecuadorian Oil Pipeline System (SOTE) by 900%, lifting the fee from $3 to $30 per barrel. The move came in response to Colombia’s decision to suspend electricity exports to Ecuador from Feb. 1, 2026.

Bogotá has yet to issue an official response to the tariff increase.

The dispute has widened beyond trade into energy cooperation and crude transportation, straining relations between the two countries amid longstanding tensions over border security and cooperation against drug trafficking.

Without explicitly referring to the trade conflict, Colombia’s Ministry of Mines and Energy last week issued a resolution suspending international electricity transactions (TIE) with Ecuador, describing the measure as a preventive step aimed at protecting Colombia’s energy sovereignty and security amid climate-related pressures on domestic supply.

Colombia is a key electricity supplier to Ecuador, particularly during periods of drought. Ecuador has faced prolonged power cuts in recent years, including in 2024 and 2025, in a country where roughly 70% of electricity generation depends on hydropower.

Colombia’s leftist President Gustavo Petro said his country had previously acted in solidarity during Ecuador’s worst drought in decades. “I hope Ecuador appreciated that when it needed us, we responded with energy,” Petro said last week.

Ecuador’s Environment and Energy Minister Inés Manzano said the crude transport tariff increase applied to Colombia’s state oil company Ecopetrol and private firms exporting oil through the SOTE. “We made a change in the tariff value,” Manzano said. “Instead of three dollars, it is now 30 dollars per barrel.”

According to Ecuadorian news outlets, the SOTE transported nearly 10,300 barrels per day of Colombian crude in November, shipped by Ecopetrol and private companies.

Manzano has also said Ecuador will impose new fees on Colombian crude transported through the Oleoducto de Crudos Pesados (OCP) pipeline, citing reciprocity following Colombia’s suspension of electricity exports.

The trade conflict began last week when Ecuadorian President Daniel Noboa, a close political ally of U.S. President Donald Trump, announced a 30% tariff on imports from Colombia, effective from February. Speaking from the World Economic Forum in Davos, Noboa said the measure was justified by what he described as insufficient cooperation from Bogotá in combating drug trafficking and organised crime along the shared border.

“We have made real efforts of cooperation with Colombia,” Noboa said in a post on social media, adding that Ecuador faces a trade deficit of more than $1 billion with its neighbour. “But while we insist on dialogue, our military continues confronting criminal groups tied to narcotrafficking on the border without cooperation.”

Colombia’s foreign ministry rejected the move as unilateral and contrary to Andean Community (CAN) trade rules, sending a formal protest note to Quito. Bogotá has proposed a high-level ministerial meeting involving foreign affairs, defence, trade and energy officials to de-escalate the dispute, though no date has been confirmed.

Colombia’s Ministry of Commerce, Industry and Tourism (MinCIT) responded by announcing a 30% tariff on 23 Ecuadorian products, which have not yet been specified, with the option to extend the measure to additional goods. Trade Minister Diana Marcela Morales Rojas said the tariff was proportional, temporary and intended to restore balance to bilateral trade.

“This levy does not constitute a sanction or a confrontational measure,” the ministry said in a statement. “It is a corrective action aimed at protecting the national productive apparatus.”

Business groups say Colombia exports mainly electricity, medicines, vehicles, cosmetics and plastics to Ecuador, while importing vegetable oils and fats, canned tuna, minerals and metals. Ecuador’s exporters federation, Fedexpor, said non-oil exports to Colombia rose 4% between January and November last year, with more than 1,130 products entering the Colombian market.

Colombia and Ecuador share a 600-kilometre border stretching from the Pacific coast to the Amazon rainforest, a region where Colombian guerrilla groups and binational criminal organisations operate, including networks involved in drug trafficking, arms smuggling and illegal mining.

Although Quito and Bogotá have both signalled willingness to engage in dialogue, the rapid escalation of tariffs and energy measures has raised concerns among exporters, energy producers and regional analysts about the risk of prolonged disruption to trade and cooperation between two of the Andean region’s closest economic partners.
