Paraguay's President Santiago Peña wrapped up a four-day state visit to Taiwan on May 10, signing cooperation agreements on cybersecurity and legal assistance, receiving the island's highest civilian honour and announcing, with characteristic fanfare, a joint AI computing hub that exists so far only as a social media post. The diplomacy was warm. The economics remain brutal.

Peña has now visited Taiwan three times as president. The choreography is consistent: military honours, honorary doctorates, declarations of shared values, a business delegation in tow. Taiwanese President Lai Ching-te welcomed him with cannon salutes and a red carpet. More than 40 Paraguayan business representatives made the trip. The two governments framed it as a deepening alliance. Beijing called it provocative.

China's Foreign Ministry urged Asunción to "stand on the right side of history" and sever ties with Taipei. Spokesperson Lin Jian cited the One China principle as accepted by 183 states. This is boilerplate, but the operational pressure is anything but. Reuters has documented a sustained Chinese lobbying campaign targeting Paraguayan lawmakers and journalists: at least 19 parliamentarians and five journalists have visited China since late 2023, many hosted through the Chinese consulate in São Paulo, with extravagant banquets and luxury hotel stays included. The template is identical to the one successfully deployed in Honduras, Nicaragua, Panama and El Salvador.

What makes Paraguay different is not rhetoric but arithmetic. But that arithmetic is increasingly uncomfortable for Asunción. Chinese goods flooded Paraguay in 2025, with imports topping a record $6bn. Yet Paraguay cannot export directly to China because Beijing refuses trade with any state recognising Taipei. Beef — which generated $2.1bn in export revenues in 2025, according to Senacsa — reaches Chinese consumers only via third-country re-routing, eroding margins. Soy is the same story: Paraguay is one of the world's top ten producers, China is the world's largest buyer, and Asunción cannot access that market directly. Both sectors are acutely aware of what diplomatic exclusivity costs them in practice. The agricultural export lobby, whose frustration is mounting, is the genuine fault line in Paraguayan domestic politics on this issue — not parliamentary junkets to Beijing.

Taiwan offers something real but structurally limited: $288mn in beef imports last year, a zero-tariff pork deal concluded in 2025, aid, infrastructure, predictability. The AI hub announcement — a purported 50/50 joint venture to build one of the world's largest computing centres, combining Taiwanese semiconductor capacity with Paraguayan hydroelectric surplus — is best read as a political intervention in that domestic debate rather than a credible near-term investment. No location, no timeline, no capital figure and no engineering study have been made public. Peña announced it via social media on his way home.

The Mercosur dimension adds a layer that rarely gets adequate attention. Paraguay's recognition of Taiwan effectively vetoes any China-Mercosur trade framework, frustrating Buenos Aires and Brasília. That veto has costs and constituency implications that extend well beyond Asunción's bilateral calculus.

Paraguay is now Taiwan's only South American ally and one of just 12 states worldwide, seven in Latin America and the Caribbean, maintaining formal diplomatic relations with the disputed self-governing island-nation. The alliance dates to 1957. Since 2021, Honduras and Nicaragua have switched to Beijing, following a well-worn regional pattern.

The Peña government's calculation is coherent within its constraints: Chinese goods already flood Paraguay without any diplomatic recognition, so the marginal gain from switching is not current market access but the enticing prospect of direct beef and soy exports at scale. Such a prospect is real, and the agricultural sector knows it. As a result, what keeps the right-wing Colorado Party in Taipei's camp is not sentiment but the absence, so far, of sufficient electoral pressure from exporters to make switching worth the political cost. That calculus is not permanent.
