Argentine President Cristina Kirchner announced the withdrawal of her ambassador to Paraguay, citing "grave institutional events" and saying the embassy's No. 2 will remain in charge "until democratic order is re-established in that country."
The Cuban government said Saturday it wouldn't recognize the new government and called Lugo's removal a "parliamentary coup d'état executed against the constitutional President Fernando Lugo and the brother people of Paraguay."
Criticism came not just from the left but from conservative governments, too.
Chile said Lugo's removal "did not comply with the minimum standards of due process," and Colombian President Juan Manuel Santos said "legal procedures shouldn't be used to abuse. ... What we want is to help stability and democracy be maintained in Paraguay."
Given the tough talk, Franco could find mending fences to be a tall order.
"It looks terrible throughout the region," said analyst Adam Isacson of the Washington Office on Latin America, a think tank. "[Lugo's ouster] doesn't look like a deliberative process, and what it looks like is that a president can be removed simply for being unpopular, or making unpopular decisions."
"The new government is going to be pretty isolated for the whole time that it's in power," Isacson said. "For Paraguay's neighbors and trade partners, I think there's probably not great cost involved in isolating the country for a year or more, and then re-recognizing whatever government is elected next year."
