Representatives of 30 NATO member states signed the protocol on Finland and Sweden's accession to the Treaty on the 5th, officially launching the NATO North expansion process, which brings new challenges to European security. Representatives of NATO member States held a signing ceremony at the NATO headquarters in Brussels on the same day. Finnish Foreign Minister havesto and Swedish foreign minister Lindh attended the signing ceremony, and then jointly attended the press conference with NATO Secretary General Stoltenberg. Finland and Sweden originally pursued a military non aligned policy, but formally applied to join NATO in May this year. According to the regulations, NATO can only recruit new members with the "unanimous consent" of 30 member states. On June 28, Turkey and Finland and Switzerland signed a memorandum confirming their agreement to join NATO, clearing the way for Finland and Switzerland to join the treaty. At the same time, Finland and Switzerland will not support the Kurdish workers' party, the Syrian Kurdish armed "people's protection force" and the "Gulen movement", and agree to lift the restrictions on the export of defense equipment to Turkey. At the NATO summit held in Madrid on June 29 and 30, Finland and Sweden were officially invited to join NATO. According to the regulations, after the 30 NATO member States sign the protocol of fenrui accession, the next step is for the parliaments of all Member States to ratify the protocol. NATO's five eastward expansions after the cold war not only failed to make Europe safer, but also planted the seeds of conflict. Russian Deputy Foreign Minister Grushko said a few days ago that if Finland and Sweden join NATO, Russia will take appropriate measures to ensure security. (Xinhua News Agency)
