Negotiations between Turkey and the delegations of Sweden and Finland this week made little progress in overcoming Ankara's objections to the Nordic countries joining NATO. It is not yet known when negotiations between the countries will continue. This was reported by Reuters.

"It's not an easy process. They have to take concrete steps, which will not be easy. Further negotiations will continue. But the date does not seem very close," a senior Turkish official said.

A source close to the situation said the talks made no apparent progress and ended without any timetable for continuation, raising the possibility that Turkey may still oppose Sweden and Finland's candidate status offer at the Madrid summit in late June.

The five-hour discussions were cordial and included separate meetings between Turkish officials and counterparts from the two Scandinavian countries, followed by trilateral talks with all sides.

A third source told the publication that Turkish officials downplayed the prospects of reaching an agreement before the Madrid summit.
