Turkish President Recep Tayyip Erdogan has warned to freeze the NATO expansion in Sweden and Finland if they fail to fulfill their agreement.
Turkey has demanded that Sweden and Finland end the embargo on arms sales to Turkey and punish the rebels of the Kurdistan Workers’ Party, taken refuge in Sweden and Finland who have been declared terrorists by Turkey.
Until the end of June, Turkey blocked the invitation of Sweden and Finland to become NATO members, but after the trilateral memorandum signed in Madrid, it allowed Sweden and Finland to be formally invited to the summit in Spain. However, Erdoğan has been saying that he will stop both countries from joining NATO until the demand is met, saying that Turkey’s stance on it’s demand remains.

Although Finland and Sweden remained neutral during the Cold War, both countries applied to join NATO on May 18 amid security concerns following the Russian military invasion of Ukraine. They can only be the members if approved by the parliaments of the 30 NATO countries.

After the US House of Representatives adopted the text of the National Defense Authorization Act that would require Turkey to submit additional certifications before buying F-16 fighter jets, Erdogan is said to have issued a conditional warning to Sweden and Finland to join NATO
Meanwhile, US President Joe Biden has said that Turkey should not play the F-16 “quid pro quo” for the Nato expansion in Sweden and Finland . He also said that said he could get congressional approval for it.
