Peru's Congress has approved a motion to expel the Venezuelan ambassador, Diego Molero.
The parliament voted in favor of the proposal presented by the legislator Jorge Del Castillo by 75 votes to 9.
Del Castillo said it was a "Latin American decision, of solidarity, in support of the Venezuelan people, suffering at this time and in rejection of the dictatorship."
But the final decision rests with the Peruvian President Pedro Pablo Kuczynski.
Earlier this week, Peru called a meeting to implement 16 new measures to further isolate the Venezuelan government.
Representatives from 17 countries including Chile, Mexico, Colombia, Argentina, Brazil, Paraguay, Uruguay and Costa Rica, as well as Jamaica and Guyana signed the Declaration of Lima.
The agreement qualifies the Venezuelan President Nicolas Maduro as a "dictator" and rejects the newly elected Constituent Assembly.
It also refuses to acknowledge any legalislation that does not come from the opposition-controlled National Assembly.
The Venezuelan Foreign Minister Jorge Arreaza has issued a formal protest to the ambassadors of the nations which took part in the Lima meeting.
Arreaza said it was "an affront to Venezuela's sovereignty and the 8 million people who voted in the Constituent Assembly."
He added that the ambassadors acknowledged that the country has been peaceful since the poll on July 30.
And they recognized that candidates from across the political spectrum had enrolled to participate in the regional elections in December.
While Arreaza expressed Venezuela's "absolute rejection" of the attempts to isolate Caracas, he reiterated Maduro's call for a new meeting of the Community of Latin American and Caribbean states, CELAC, in an effort to rebuild regional dialogue.
