Nicaragua's Parlacen withdrawal deepens its regional isolation

Nicaragua's Parlacen withdrawal takes effect immediately, the foreign ministry in Managua said in a statement on Saturday, denouncing the 1987 treaty that created the six-country Central American Parliament "in the full exercise of its sovereignty," according to Reuters. The announcement came one day after the Organization of American States adopted a resolution calling on Nicaragua to free political prisoners and restore civil liberties, and it pushes the country further into diplomatic isolation as rights groups document a years-long crackdown on dissent.

A break with the OAS

The OAS resolution, adopted on Friday, sets up a ministerial follow-up group that will engage with Nicaraguan officials and exiles before returning with recommendations for concrete measures within 90 days. U.S. Deputy Secretary of State Christopher Landau, who attended the meeting for Washington, framed the crisis as a hemispheric security concern. "We all understand that the democratic crisis in Nicaragua isn't solely an internal matter; to the contrary, the dictatorship endangers the peace and security of our hemisphere," he said. Landau also accused non-hemispheric security services of training Nicaraguan police and sharing intelligence with them. Nicaragua formally left the OAS in 2023, describing the body as a tool of U.S. interventionism.

The Parlacen withdrawal continues a pattern of shedding international commitments. In 2025, Managua said it would leave the United Nations Human Rights Council after a U.N. report urged the international community to address rights violations in the country. In July, lawmakers aligned with President Daniel Ortega moved to carry out his plan to abolish elections entirely, with Ortega declaring that "there won't be anymore elections." U.N. human rights chief Volker Türk condemned the move, saying that "people of all political viewpoints must be allowed to vote and run for office." The canceled vote had been scheduled for November 2027, after the government-controlled congress voted to extend the five-year presidential term by one year.

A crackdown years in the making

The crisis traces back to April 2018, when nationwide protests against the government were suppressed by police, leaving more than 350 people dead, 2,000 injuries and thousands detained or forced to flee the country, according to Reuters. Since then, the government run by Ortega and his wife, co-President Rosario Murillo, has jailed opposition politicians and religious leaders and shut down thousands of civil society organizations, the Associated Press reported. Congress has repeatedly rewritten the constitution to concentrate power and eliminate democratic checks, leaving civic space in the country nearly closed. The Parlacen withdrawal is the latest diplomatic fallout from that crackdown.

Ortega has held power continuously since 2007, following an earlier presidential term in the 1980s. He now governs alongside Murillo under a co-presidency that has concentrated authority in the couple's hands, drawing condemnation from the U.N. rights office. Independent expression of thought or opinion is systematically suppressed, Türk warned this summer, and at least 46 people remained arbitrarily detained for political reasons when he spoke.

What the Parlacen withdrawal changes in practice is limited. Parlacen is a largely consultative regional body with little binding authority, and Managua has long ignored regional criticism. The symbolism is what matters: each exit closes another channel through which outside governments and advocates could pressure the country, and the foreign ministry framed the Parlacen withdrawal as an act of sovereignty rather than a response to the OAS vote. The practical question now is whether the OAS follow-up group produces concrete measures or just another round of statements like the ones that followed every previous escalation.

For the region's younger generation, the Nicaragua story is a case study in how quickly a democracy can close. Elections are gone, international bodies are being shed one by one, and the Parlacen withdrawal leaves Guatemala, El Salvador, Honduras, Panama and the Dominican Republic as the parliament's remaining members. Rights groups that spent years documenting arbitrary detentions, forced exile and the denationalization of critics are watching whether regional diplomacy has any lever left, or whether Nicaragua has simply finished walking away.
