Sweden and nine other countries made a joint statement on Monday.
Among other things, it was written that the imprisonment of Osman Kavala "casts a shadow" over Turkey.
The Turkish Foreign Ministry responded by calling, among others, the Swedish ambassador Staffan Herrström on Tuesday.
Now President Erdogan is sharpening his tone further.
"I have told our Foreign Minister that we do not have the luxury of hosting them (the ambassadors) in our country," he said in a statement to the Turkish media.
Osman Kavala has been detained since 2017 and is accused, among other things, of having organized protests in 2013 against the rebuilding of the Gezi Park in Istanbul.
He was released in February 2020, only to be arrested again a few hours later - this time on suspicion of involvement in the 2016 coup attempt.
Sweden, together with Denmark, France, Finland, Canada, the Netherlands, Norway, New Zealand, Germany and the United States, wants Kavala to be released immediately.
- Is it really your place to teach Turkey such a lesson?
says Recep Tayyip Erdogan to the Turkish TV channel NTV.
Activist: "A good story"
When Kavala was interviewed by AFP in prison last week, he said he sees himself as a pawn in Erdogan's political game against the West.
"The real reason for my continued deprivation of liberty is that the government needs to keep alive a fictional story that the Gezi protests were the result of a foreign conspiracy," said the businessman and activist.
- My release would weaken that story and it is not something that the government wants.
