Visiting Buenos Aires is a tradition for Brazilian leaders dating back to 1900, when then-President Campos Salles visited Julio Argentino Roca. On Thursday, Jair Bolsonaro became the 13th Brazilian president to pay a visit to our neighbors. The visit was marked by Mr. Bolsonaro’s breaches of protocol and unapologetic bravado.
International leaders usually avoid endorsing candidates in other countries’ elections—especially tight races—for one simple reason: they will have to deal with whoever wins. The Brazil-Argentina relationship is key to both countries, as our neighbors are Brazil’s third-biggest trading partners (trailing behind only China and the U.S.), and one of the main destinations of manufactured goods produced in Brazilian factories.
