A sourced chronology of diplomacy, agreements, security arrangements, economic cooperation and mobility.

Counting & sources

This is a curated register, not an exhaustive count. Each event has one primary category and is counted once within this monitor. Repeated reports and translations do not create extra events. Shared developments may appear in related monitors and must not be added together as unique events. Counts measure recorded developments, not policy success or democratic quality. Gaps do not establish inactivity.

Official statements establish what the issuing body recorded or announced. They do not by themselves prove that every commitment was fulfilled. Event dates drive charts; later publication dates are retained separately. The register is selective and will need further additions.
