This decision had been taken as part of a deal reached by the Lima Group aimed at countering the Venezuelan government, the official added, as cited by the Republic news outlet on Wednesday.
Kruger added that the campaign against Caracas currently included measures that had been tentatively agreed upon, while the scale of the sanctions might be increased, according to the outlet.
The publication added that Venezuelan national Ronald Ramirez was the first person denied entry to Colombia after he landed in the Barranquilla airport.
Venezuela is currently facing a political crisis and large anti-government protests. Opposition leader Juan Guaido has declared himself as the country's interim president, drawing support from the United States and a number of its allies and prompting harsh criticism on the part of Venezuelan President Nicolas Maduro, who called Guaido a "US puppet".
The UK, Germany, France, and Spain declared on Saturday their intention to recognise Juan Guaido as the country's interim president if Caracas does not announce snap presidential elections within eight days. Several members of the Lima Group — Canada, Chile, Argentina, Brazil and Columbia have also recognized Guaido as Venezuela's interim president.
In turn, Russia, Cuba, China, Turkey and Iran have given Maduro's government full support, with Maduro himself calling Venezuela "the victim of a US conspiracy", referring to US Vice President Mike Pence promising Guaido "full American support" the day before he declared himself Venezuela's new head of state. Maduro also stressed that Venezuela had held legitimate elections and urged European countries to withdraw their demand.
