Christopher Landau, US Deputy Secretary of State for Western Hemisphere Affairs, begins a tour of Paraguay and Argentina today with an economic pitch in hand. The trip runs through October 26 and pairs Landau with Juan Pablo Segura, an Argentine-born businessman appointed Principal Deputy Assistant Secretary for the region last August. Washington’s message is blunt: private capital and security cooperation go hand in hand.
The Agenda
The two officials are scheduled to meet Foreign Minister Pablo Quirno at the San Martín Palace in Buenos Aires at 2pm next Thursday. Casa Rosada announced their arrival through official channels on Sunday. A State Department statement said Landau would meet "senior Argentine government officials and private-sector leaders."
Look at the guest list’s order. Business sits alongside government, not behind it.
The agenda brings commerce and security together, which the report described as central pillars of Donald Trump's new security doctrine, designed to keep outside powers from gaining a foothold in the hemisphere. Before the tour, Landau appeared with Quirno in New York, where the two signed the Andes-Atlantic Corridor infrastructure agreement.
Capital Over Aid
Announced on September 23 during the latest United Nations General Assembly, the corridor envisages US investment in railways, waterways, ports, oil pipelines and energy infrastructure. Vaca Muerta's shale reserves and the mining sector sit at its core. The initiative forms part of US strategic competition with China.
Segura, the son of Argentine immigrants, said the delegation will seek "ways to drive economic growth, increase US investment and strengthen security cooperation." He singled out "narcoterrorism" as a "threat to countries' sovereignty." In an interview with El Observador days before departing, he laid out the philosophy plainly: "One of the strongest tools the United States has is economic power. We are seeing that in Argentina."
The tour opens in Asunción, where Santiago Peña has emerged as a leading proponent of the Trump administration's policy of "containing Chinese interference."
Security Dollars
The security effort comes with figures attached. On October 5, the National Security Ministry announced that the United States had approved US$13.35 million in funding and that a regional unit of the State Department's anti-narcotics office would be established in Argentina. The ministry offered no further details about its operations. Of the total, US$7.5 million would go to projects in Argentina, while officials allocated the rest to "regional initiatives." That makes current cooperation ten times larger.
The State Department said Landau's visits "reflect the Trump administration's commitment to a safe, secure and prosperous Western Hemisphere."
Milei's Calendar
One notable absence: Landau isn't expected to meet President Javier Milei. Presidential spokesperson Adrián Ravier said Milei is due to arrive in Spain on October 21, where he plans to strengthen ties with conservative international allies ahead of elections Pedro Sánchez called for November.
The visit comes amid what the report described as exceptionally close relations between Washington and the Casa Rosada. Milei had just returned from his second US visit in a month. During a 36-hour stay, he received the US Chamber of Commerce's "World Champion of Free Enterprise" award. He didn't get a photograph with Trump, but said he had spoken by telephone with US Secretary of State Marco Rubio. He also attended a gala organized by La Derecha Diario and the Heritage Foundation, which the report called a controversial think tank behind Project 2025 and linked to US Vice-President JD Vance.
Vance himself is scheduled to travel to Argentina after the US midterm elections on November 5. The report said this would mark the first visit by a US vice-president since Mike Pence's trip in April 2017. The Casa Rosada confirmed it would be "a regional visit," potentially in the third week of November, based on reports the White House hasn't yet confirmed.
Why This Matters:
The Landau-Segura tour shows Washington betting on investment rather than handouts to anchor its position in South America. A corridor built on private US capital, energy and mining brings commercial discipline that traditional aid rarely does, while giving Buenos Aires a market-driven alternative to Chinese financing. But the security component deserves scrutiny: the ministry has released few details about how the new anti-narcotics unit will operate or how officials will track the money. Taxpayers on both sides will want answers. For Argentina, the opportunity is real, but clear rules, transparent contracts and a stable investment climate are also needed if the corridor is to deliver more than headlines.
