US Secretary of State, Antony Blinken, is set to discuss multiple areas of bilateral and regional cooperation, including the final steps for Turkey's ratification of Sweden's NATO membership, with his Swedish counterpart, Tobias Billström.

The talks come amid concerns that if Sweden's NATO membership is not approved by this summer, it could remain in limbo for years.

Experts suggest that the NATO summit in July is a crucial deadline.

If membership is not granted then, it could take years for the next opportunity.

Although Turkey has given approval at the foreign committee level, the final decision has not yet been made.

The situation is further complicated by the upcoming US presidential election in November and potential changes in relations between Turkey, Russia, and the US.
