This has been going on for over a week now, but appears to be approaching the breaking point.
The U.S. currently has a press conference with John Bolton announcing economic sanctions.

The countries that support Venezuelan president Nicolás Maduro or opposition leader Juan Guaidó

By Daniel Wolfe, January 24, 2019


After massive protests of Venezuela president Nicolás Maduro yesterday (Jan. 23), national assembly speaker Juan Guaidó swore himself in as the nation’s interim leader, giving the South American country two heads of state. Shortly after, the US recognized Guaidó’s move, followed by 11 other nations—Argentina, Brazil, Canada, Chile, Colombia, Costa Rica, Guatemala, Honduras, Panama, Paraguay, and Peru—as well as the EU.

The US stance prompted Maduro to issue a 72 hour window for American diplomats and consular staff to leave the country. “The imperial government of the United States is leading a coup attempt against [Venezuela] in order to install a puppet presidency…” said Maduro during a live state broadcast.

Russia, Bolivia, and Cuba issued statements supporting Maduro as the legitimate president.
Meanwhile, China issued a statement opposing foreign interference in Venezuela. “I want to emphasize that outside sanctions or interference usually make the situation more complicated,” foreign ministry spokeswoman Hua Chunying said at a Beijing briefing.

As more countries rally behind the two presidents, pressure for change may reach a tipping point. Ignoring Maduro’s threat, US secretary of state Mike Pompeo said US diplomats would remain in the country, cooperating with Guaidó. Issuing his own warning, Pompeo told CNN, “the United States will take appropriate actions to hold accountable anyone who endangers the safety and security of our mission and its personnel.”



The nations supporting Maduro over Guaido are either communist regimes, and/or nations that kneejerk oppose any policy the U.S. supports.
