This week, hundreds of parliamentarians from Europe, North America, and Central Asia will be gathering in The Hague for the Annual Session of the Organization for Security and Co-operation in Europe Parliamentary Assembly (OSCE PA). The meeting is being organised by the Senate and the House of Representatives of the Netherlands and will be held from 4 to 8 July in the World Forum in The Hague.

How can international law and shared principles provide the foundations for shaping security and cooperation in an age of geopolitical tensions? This will be the key question during the Annual Session. The parliamentarians will be debating current crises, including the war in Ukraine, tensions in the Middle East, and the increasing pressures on democratic values.

International law institutions

As well as political leaders, representatives from international law institutions will also speak at the meeting. This includes Tomoko Akane, the President of the International Criminal Court, and Boštjan Škrlec, Eurojust Vice-President, who will open the plenary debate on Tuesday 7 July. The main theme of the debate will be the role of international law.

Declaration of The Hague

Feridun Sinirlioğlu, the OSCE Secretary General, will speak on the final day, Wednesday 8 July. This will be followed by the adoption of the Declaration of The Hague, in which parliamentarians will set down joint agreements on security, cooperation, and strengthening the rule of law.

Wide-ranging agenda
