FIRST ON FOX — El Salvador has reported a drop in crime and a decrease in migration out of the country after years of bearing the title "the murder capital" of the world, the country’s vice president told Fox News Digital. 

"We are very clear exactly what is our policy regarding enforcing immigration," Salvadoran Vice President Félix Ulloa told Fox News Digital. "President [Nayib] Bukele has been clear from the very beginning. This is not a problem of the United States only: This is our problem."

"We don’t want to hide the problem," Ulloa added. "We won’t try to put the trash under the carpet. We will face the problem. This is a problem that has been created for and by the exclusion — social, economic exclusion — and boosted by the violence in the community. So we have to deal with that."

Ulloa called immigration "a permanent issue" and urged the U.S. to develop a comprehensive, bipartisan plan to "manage this issue." To that end, he said his country reached out to the U.S., sending a letter to Vice President Kamala Harris to request a dialogue over a potential $4 billion investment in the region to create jobs and help increase quality of life so that it might deter people from leaving the country.

However, Harris did not respond to that letter, Ulloa said, underscoring the need "to solve the problems in the countries" where the immigrants originate. At the time of publication, Fox News Digital could not verify the vice president's response to the letter as Harris' office did not respond to several Fox News Digital requests for comment.

Harris has been the point person for the administration’s efforts to address root causes of migration from a few Central American countries, including El Salvador, per a White House fact sheet shortly after President Biden took office.

In February, the administration announced a roughly $1 billion investment in communities in those countries through companies including Nestle, Target and Columbia Sportswear to support farmers, create textile jobs and invest in various industries, The New York Times reported. 

Ulloa argued that El Salvador is "not only obligated," but also has "the right to maintain this harmonious relations with the administration … doesn’t matter which is the side of Democrats or Republicans. It is the U.S. government in place." He believed that El Salvador’s success could serve as a blueprint for other countries in the region, but that more work is needed, and that help would require cooperation with the U.S. — but the two nations have experienced some tension.

Biden administration officials turned down a meeting request with Salvadoran President Nayib Bukele in February during an unannounced Washington trip following an alleged snub from Bukele in 2021 against U.S. diplomat Ricardo Zuniga. Ulloa dismissed any continued rumblings of disagreement, saying that his country has been "keeping in all diplomatic relations."

"It’s a misunderstanding with some of the envoys that came in the past," Ulloa said. "But now the relationship has been improved and we have an excellent relations with the ambassador.

"We want to maintain the open dialogue, the demonstration with this administration, with the new administration that could take over the obviously being intellectual, because our relationship with the United States Is a long story, probably a long life."

Ulloa suggested that Secretary of Homeland Security Alejandro Mayorkas look to overhaul and improve the process by which immigrants can apply for citizenship and more easily manage the process. The Department of Homeland Security referred a Fox News Digital request for comment to the State Department.

A State Department spokesperson told Fox News Digital that the U.S. is increasing assistance to host countries "throughout the Western Hemisphere" to help "integrate refugees and migrants and provide assistance and protection" to migrants.  The spokesperson stressed that they could not provide further details of diplomatic discussions, but said the U.S. is committed to working with regional partners to expand access to "lawful pathways."

"The United States is also making lawful pathways for migration more accessible from within South and Central America," the spokesperson explained. "In April, Secretary Blinken and Secretary Mayorkas announced sweeping new measures to address the irregular migration flows at the U.S. southwest border by expanding lawful pathways to the United States including for protection, certain parole programs, family reunification and labor pathways."

Ulloa believes, though, that El Salvador's success with reducing crime and allegedly reducing the outflow of migration could serve as a blueprint for other countries in the region. He revealed that some countries have reached out to El Salvador regarding the mega-prison, whom he could not name, but did say his country has "offered to do some technical training and technical assistance" to other countries "that require this type of thing." 

"I said it in the U.N. in New York, I said it in other summits, in different summits of the countries of the region, that El Salvador is willing to share our experience because the good practices should be shared, wherever that's needed," Ulloa said. "We are open to receive from any country or any international body, any request to share our technical assistance in this regard."

"If any country is interested, they could come, they could ask for an appointment with the Minister of Justice or with the director of the penal system, or directly with our ministers," he added.

Ulloa referred to comments by U.S. Ambassador to El Salvador William H. Duncan that suggested the country has seen a 40% decrease in people leaving the country over the past year — partially after the establishment of the country’s mega-prison "Terrorism Confinement Center."

The prison, which can hold 40,000 people, has already exceeded 10% capacity just a few months after opening, with tens of thousands of gang members still waiting for trial. Ulloa said the prison was necessary after his country received criticism for being overrun by criminals to the point that "the traditional penitentiary system was overcrowded."

"In the past, there were a lot of escapes, because of the way that the penitentiary system and all the facilities were built," Ulloa explained, noting that a number of the buildings were from colonial times.

The new mega-prison, which Ulloa said the country built in "record time," involves "new technologies." He noted that one of the significant issues that the country faced was the proximity of jails to cities, so it was necessary to build the mega-prison in an isolated area.

Ulloa said the prison would contain the facilities for inmates to train in workshops and potentially even farm their own food and produce "something to be sold out of the prison." 

"In that way, they could be self-sustaining," Ulloa claimed. "It has been a model for other countries, who have come to visit and check to see how [it] was and how [it] is working now."
