Brazil and China have gone from a single feasibility-study memorandum to separate, unconnected national contracts — Peru's $420 million PowerChina deal and a new Brazilian rail tender — while the trans-Andean link joining them still has no construction date.
- The favored route runs roughly 4,000 kilometers from the Atlantic port of Ilhéus to the Chinese-built Chancay megaport, sidelining an older Bolivia-routed alternative first proposed in 2013.

Independent research estimates freight costs via Chancay could run up to 117% above existing Brazilian shipping routes, with at least 15 protected natural areas mapped along the corridor's possible paths.
A decade-old dream of threading a railway across South America from the Atlantic to the Pacific is edging closer to reality, one disconnected piece at a time. Argentine outlet Canal 26 revisited the project this month, more than a year after Brasília and Beijing formally relaunched talks in July 2025. Since then, contract awards, public tenders and technical studies have started giving shape to a route that still carries no opening date.
Two Competing Routes: The Chancay Corridor and the Bolivia Alternative
The plan getting the most traction right now would connect the port of Ilhéus, in Brazil's Bahia state, to the Chinese-built Chancay megaport in Peru, cutting through the Brazilian states of Goiás, Mato Grosso, Rondônia and Acre before crossing into the Peruvian Amazon on a route stretching more than 4,000 kilometers in a straight line. A separate, older proposal — the Central Bi-Oceanic Railway Corridor, which Bolivia and China first discussed in 2013 — would instead link the port of Santos with Peru's Ilo, running through Bolivian territory, with a price tag estimated at roughly $10 billion. The memorandum Brasília and Beijing signed steers traffic toward Chancay instead, leaving the Bolivian option as a secondary route for future expansion. Peru isn't formally part of the original deal at all — economist Santiago Roca argued in a La República column that the country should demand its own rail network rather than settle for being mere transit territory.
From Blueprints to Steel: What's Already Being Built
While the international link stays theoretical, each country is advancing its own stretch independently. In January 2026, Peru awarded PowerChina, the state-owned Chinese construction giant, a $420 million contract to design and build a 120-kilometer branch linking Chancay with the country's central highlands, with a roughly 36-month build window and an operational target of 2028. In Brazil, the Ministry of Transportation published a tender in September 2025 for a new 35.7-kilometer stretch of the West-East Integration Railway (FIOL) in Bahia, budgeted at 507.1 million reais — roughly $92 million — with construction slated to begin in mid-2026.
No Official Timeline, But the Clock Is Ticking
There's still no schedule for the international stretch that would actually cross the Andes and the Amazon. Brazil originally figured the feasibility studies alone could take five to ten years, but bringing China in cut that estimate down to 18 to 20 months, Planning Minister Simone Tebet told Brazil's Chamber of Deputies. Tebet has set a goal of having the project ready by late 2026, while making clear that the decision on whether to actually build it rests with Brazil's next government.
The five Brazilian states along the proposed route exported a combined $22.4 billion in goods to China in 2025 — 22% of everything Brazil sells the country — led by soybeans at $15.6 billion, according to a trade-data analysis by Dialogue Earth. Backers say the railway could shave up to ten days off shipping times to Asia. In Peru, mining-sector estimates point to annual logistics savings above $1.5 billion once the Chancay–Sierra Central branch is operating. The full bioceanic corridor in its original, Bolivia-linked form has long carried a roughly $10 billion estimate dating to studies from the previous decade — a figure no government has confirmed for the current Chancay-centered design, which separate reporting has priced anywhere from $18.5 billion to well over $50 billion depending on scope.
Environmental and Profitability Doubts
Not everyone is convinced the math works. Research from the University of the Pacific's Center for China and Asia-Pacific Studies, reported by Ojo Público, found that freight moving through Chancay could cost up to 117% more than shipping via existing Brazilian routes, and that the proposed path would cut through more than a dozen protected natural areas. Researchers interviewed by Mongabay Latam have separately warned about the impact on Indigenous communities in the Peruvian Amazon, while Ucayali's own regional government acknowledges that no final route or approved environmental impact study yet exists.
Peru's Balancing Act Between Opportunity and Geopolitical Caution
The PowerChina award has reignited concern in Washington over growing Chinese control of strategic infrastructure in Peru, Infobae reported. The Chancay–Sierra Central branch is projected to generate work for more than 8,000 Peruvians during construction, though environmental group CooperAcción has publicly challenged that figure as inflated and called the 2028 completion target unrealistic — skepticism echoed by shipping-industry analysts who note that much of the project's structural upside would likely flow to foreign investors rather than local firms.
For now, the bioceanic railway remains mostly a project on paper: technically promising, politically sensitive, and financially still an open question.
