Britain is “unlikely” to exclude the list of countries in the Republic of Ireland from quarantine rules, said Simon Coveney.
The Irish government is expected to publish a “green list” of countries on Monday.
Irish authorities currently require that anyone coming to the Republic of Ireland, except those from Northern Ireland, self-isolate for 14 days.
The Minister of Foreign Affairs also said there was “no doubt” that the United States would not be on the list.
Last week, taoiseach (Irish Prime Minister) Micheál Martin told Sunday Politics of the BBC NI that he had concerns about travel between Britain and Ireland.
Speaking to Newstalk radio on Friday, Coveney said the decisions were not made “on the basis of politics”.
“I think it is very unlikely that our closest neighbor [the UK] will be below this threshold that we have set, “he said.
“It’s really a shame because the two countries that we would like to open up in terms of international travel are the United Kingdom and the United States, given the integration between our economy and these two countries.
“It’s based on epidemiological data and figures, so we can compare Ireland to other countries.
“Then we can put people on a green list that we consider to be no higher risk than Ireland. ”
He added that the Irish government would review data such as the number of cases per 100,000 and would consider changing the protocols at airports.
“If the decision is made to open a green list, we also plan to work with airports to ensure a much more visible presence informing people of their obligations when they come to Ireland,” he said.

The Minister also said that the Irish government would consider making the Covid-19 test available to travelers arriving in the Republic of Ireland.
Last week, the Stormont Executive agreed to change its quarantine rules, which means that people arriving in NI from more than 50 countries no longer need to isolate themselves upon arrival.
