This week's NATO foreign ministers' meeting in Brussels will be the first with Finland as a true member of the military alliance. Sweden is continuing to work on its process, including through meetings on the side between Billström and his colleagues from Turkey and Hungary.

"I have no hopes of a major and dramatic breakthrough at this meeting, but it is a good opportunity to discuss the issues in the future," Billström told the Swedish press corps on site.

Meets Turkey

One of today's side meetings is with Turkish Foreign Minister Mevlüt Cavusoglu.

"The message will be that we have done our part of the bargain. On the first of June, new legislation will come into place that will mean that we forcefully complicate and prevent Swedish territory from being used for terrorist activities and, of course, also for the financing of terrorist activities. After that, we don't see that there is anything else left," says Billström.

"Says nothing about religion"

And trying to imitate the law that Finland has on peace of faith, to stop, for example, Koran burnings, Billström does not see as an alternative for Sweden.

– No, it is not relevant. I would also like to underline that in the memorandum that we signed with Turkey (on the NATO process) there is no mention of religion, nothing of that kind of thing. We intend to do what we have committed ourselves to within the framework of the memorandum. But nothing more, nothing less, says the foreign minister in Brussels.
