Monaghan Councillors voted down a motion that would have seen the Local Authority lend its support to ending a blockade of Cuba by the US.
Sinn Féin's Pat Treanor raised the motion after it was circulated to all councils on the island by Fermanagh and Omagh District Council.
However, while some councillors agreed with the motion, they questioned its relevancy to the County Council.
Fermanagh and Omagh District Council's Syringes for Cuba Campaign/End the Blockade motion stated its "continued opposition" to what it called the "illegal and inhumane blockade of Cuba by the USA".
The motion says "this blockade has prevented essential supplies such as fuel entering the country".
It added the blockade is restricting essential medical supplies during the Covid-19 pandemic.
The successful motion was then circulated to all councils on the island, alongside a request that they adopt a similar position.
It was brought to Monaghan County Council by Pat Treanor and supported by his Sinn Féin colleagues.
However, it was voted down by the other councillors.
While PJ O'Hanlon agreed with the motion, he said councillors should deal with "local issues".
He asked why councillors would "get involved with Cuba and the UN" and asked if there were not enough issues to deal with in Monaghan.
However, Pat Treanor said "it is an issue that affects us" as there are some Monaghan people who live in and visit Cuba and they want the Council to express support for the motion.
